Information technology is the sector that is constantly on growth in India. That is why numerous software development tenders continue to come up each now and then in the market. It is one of the ideal ways for prospective bidders to bid and win such bids to promote their business prospects.

Areas Where Software Development Tenders Work
Some of the sectors where majority of software development tenders are floated are as follows.

Higher education institutions imparting personal training and education.

Corporate offices that use personal technologies extensively.

Financial agencies like the banks where everything is computerized these days.

Government and other public sector undertakings those are steadily moving towards computerization and online transactions.

Business platforms where most of the transactions are carried out using the information technology like the stock exchange market.

Types of Software Development Tenders Floated
Any organization using personal technology for carrying out its operations will require constant monitoring of the personal for endorsement of their data and information. Such stipulations would be even more pronounced in case of the organization using any networking including local area networking or LAN, wide area networking or WAN, and even organizations using the world wide web as their carrier of information. Threats that are visaged by such organizations are –

Identity theft and data hacking;

Virus intrusion and restitution to system used in the organization;

Upgrading the abilities of the existing system;

Monitoring chances of untoward intrusion and eliminating it.

Introduction of New Software
Sometimes organizations in public and private sectors might require some new software altogether for running some systems. As the country is rapidly moving towards automation, stipulations for fresh and new software are growing steadily as well. In such cases software development tenders are the means for accomplishment of the objective. Since bids are to be won by way of competition, it gives the opportunity for the procuring bureau to get the ideal among the bidders basing on their analysis of their bids and background.

Requirements for the Bidders

Usually the procuring bureau whether public or private will make check of the eligibility and proficiency of the bidder. Hence having a good past record and market reputation is essential for any bidder.

Such bidders for software development tenders should have a evenhandedly competent team of software engineers and experts so that the procuring bureau gets the confidence that the task entrusted is in innocuous hands.

Sometimes the software development tenders are highly technical in nature. For instance; network switching, blade chassis, world wide web access server; network storage improvement, file server, security server and several others.

Usually the software development tenders are floated for the purpose of maintaining data integrity and country and endorsement of information. Prospective bidders should realize that they should have proficiency in personal technology so as to be healthy to accomplish the task.

ISQS Notes for Test 3

10/30 Motion picture Notes:

GUI- Graphical User Interface-Windows 95.

Ethernet-first computing software.

Xerox PARC Researchers- prefabricated individualized computers, but management denied the vision.

Steve Jobs had a meeting with Xerox about GUI. Jobs headed the Macintosh project while John Skulley was the president of the rest of the company.

IBM was the head of personal market in 1983.

The Macintosh was introduced in 1984 and the Mac became the first inexpensive personal with GUI.

11/6 Organizing Data and Information

Data Resource Management- a managerial activity that applies into systems technology and management tools to manage the company’s data resources.

Why demand for more and superior data?

-Competitive environment

-Powerful workstations that can handle data quickly

-More personal literate personnel

Hierarchy of Data

DatabaseàFilesàRecordsàRecord AttributesàCharactersàBits

Database-Integrated collection of logically related data elements. Personnel File, Payroll File, Department File.

File (personnel file)

Social Security, Name, Date of Hire for multiple people

Record

Social Security, Name, Date of Hire

Attribute (last name)

Capshaw

Characters (bytes)

01000011 (Letter “C” in ASCII)

Bits

0 or 1

Flat File- a plateau storing all database information in one massive two-dimensional table. They are bad.

Data Management Approaches- Traditional or Database

Traditional Approach-data is stored, organized, and processed in independent files of data records.

Problems: data duplication- have to update several files.

Lack of integration-can not combine several data files to get desired information (need to get manually and then integrate).

Data dependence- when a change is prefabricated in one of the fields, the change needs to also be prefabricated in all of programs that access that file.

Database Approach-files are consolidated into a common pool of records acquirable to many different application programs. Each application accesses only fields it needs out of a global database that contains all fields. Requires the use of a database management system (DBMS).

Database Approach Advantages: Minimal data redundancy (data duplication minimized)-redundancy is minimized or eliminated.

Data integration-can combine several data files to get desired information.

Program Data Independence-data kept separate from programming code (databases do not need to be changed if a change is prefabricated to code).

Models that represent how data can be related or linked

-Hierarchical Inverted Tree Model

-Network Model

-Relational Model-structures data using a standard tabular format (rows and columns)-tables. Tables can be “linked” on common data elements.

Data model- map or diagram of entities and their relationships. Data modeling usually involves understanding a specific business problem to be solved and examining data and information needed to deliver a solution.

Entity-Relationship (ER) diagrams-commonly used when designing databases.

-graphical descriptions of entities and the relationships between entities.

-helps in the design and management of data.

Relationships include:

One to One (1:1). One stadium houses one team.

One to Many (1:N). One team has many players.

Many to Many (N:M). Players play many games.

Entity-something you collect data about. For example an item, person, place, or thing.

-Entities can be represented in a relational database in tables.

-Each column in a plateau is called an attribute, which would be a character of an entity (field name).

-Each row in a plateau is called a record or a tuple. Each record consists of many attributes.

-Key- a field in a record that is used to uniquely refer the record.

-Composite key is used when two or more attributes are needed to uniquely refer the table.

Referential Integrity- attempts to keep a database complete without loose ends (can not delete customer if customer has a due date, can not have an person appear in a motion picture that does not exist).

DBMS

-QBE is Query by Example. Used for Query Design.

-SQL is Structured Query Language. Language used behind the scenes to perform Query Operation. It’s programming language with its own syntax.

United States: Can they take credit for Information Technology (IT) developments?

Fri, 18 Feb 2011 14:45:27 +0000

Information Technology (IT) plays a major role in the world. E-commerce and various advances in IT have prefabricated a significant impact on business operations. True globalization has come because of IT. Before discussing the country which can take credit for IT developments, let us define IT first. Several researchers define the term IT as “”an all-inclusive term that encompasses individualized and telecommunication in all their forms, whatever their use”. Information technology is the ability offered by software, hardware, and telecommunications networks to deliver data in any form to individuals and organizations. Below shows the obloquy of the people who invented the key components of Information Technology

Telephone: Telephone was invented by Alexander Graham Bell. By 1878, Bell had set up the first telephone exchange in New Haven, Connecticut.

The First electronic computer: The first electronic individualized was invented by John Vincent Ansoff. He titled it the Anatasoff Berry Computer, or the ABC. It was the world’s first electronic digital computer.

The first individualized PC — The individualized individualized (PC), which is also called the microcomputer, It was designed for use by one person. The same organisation was first developed for businesses in the primeval 1970s by Steve Wozniak & Steve Jobs.

The first world wide web based email: Personal engineer, Ray Tomlinson invented world wide web based email in 1971. The first email was sent to his friend who was sitting beside him. The first email message was “QWERTYUIOP”.

Ethernet – The physical communication technology underlying the Internet,Ethernet was created by Robert Metcalfe in 1971.

TCP/IP – In May, 1974, the Institute of Electrical and Electronic Engineers (IEEE) published a paper titled “A Protocol for Packet Network Interconnection. ” The paper’s authors – Vinton Cerf and Robert designer – described a prescript called TCP that incorporated both connection-oriented and datagram services. This prescript later became known as TCP/IP.

Internet: No single mortal or organization created the World wide web but multiple people developed the key technologies that later grew to become the Internet. Since TCP/IP is the heart of the World wide web protocols, I would state Vinton and Robert who developed the TCP/IP prescript were significant contributors.

Now let us look at the biography of the inventors. Alexander Graham Bell who invented Telephone was born in Edinburgh, Scotland, UK, and later on moved to Boston, USA. John Vincent Ansoff who invented the first electronic individualized was from New York, USA. Steve Wozniak & Steve Jobs who developed the first individualized individualized are from California, USA. Ray Tomlinson is from New York. Vinton Gray is from Connecticut, USA. Robert Kahn, who worked with Vinton to invent TCP/IP protocol, is from USA. Not only the inventors but also the US government helped in IT development. Few research states During World War II, the US government funded research into tools for calculating the trajectories of artillery shells, which led to the development of various digital individualized systems and technology Products.

Having stated that, in my view many inventors and countries contributed for IT development, but these inventions played key roles in the history of Information Technology development, and most of these are from the USA. Hence I would state United Says of USA can take the credit for Information Technology developments. Each American should be chesty of their people’s contribution to the development in IT field.

2009 Top Chinese Information Technology Outsourcing Vendors, Black Book Survey 2009 Results

Thu, 17 Feb 2011 14:47:47 +0000

2009 Top Chinese Information Technology Outsourcing Vendors, Black Book Survey 2009 Results

The 2009 Black Book of Outsourcing client experience survey investigated a subset of over 460 technology and application outsourcing (AO) contracts held by 58 of the top China-centric ITO suppliers. 18 key performance indicators (KPIs) or criteria are employed, specific to infrastructure and AO buyers within the Chinese managed IT services sector, scored on apiece respective vendor then ranked per KPI.

Key finding: most important customer satisfaction KPIs for clients utilizing China-centric vendors
Trust, innovation, customization and reliability are the most important attributes influencing client satisfaction with their Chinese outsourcing providers.

Key finding: vendor dissatisfaction is unusual in the China-centric technology area, with the applications development and software testing sectors among top ranked suppliers
Strong dissatisfaction in this geographically-specific ITO sector occurred in 17. 5% of first year clients, but only 5. 1% of clients beyond their thirteenth month or more of contracted relations. UK clients are among the most satisfied with China-centric outsourcing services delivery, averaging 87. 5% in 2009. European clients in countries other than the UK were the next most satisfied group (83. 8%) of all geographic locations, matching clients experience with vendor delivery.
Stronger dissatisfaction was more commonly reported from engagements of US clients, at 12. 4% from first year contracts. Satisfaction scores increased sharply in US clients beyond their first year of their contract arrangements.

Key finding: comprehensive services vendor arrangements from applications development vendors produce the highest satisfaction rates
Vendors offering comprehensive application services (development, management and maintenance) ranked highest in the overall survey by global clients. ITO clients showed significant preference for vendors capable of offering more extensive applications service lines once satisfied with initial projects.

Information Technology Explored as a Corporate Asset

Sun, 13 Feb 2011 21:23:32 +0000

It is a significant fact that we are in the focal point of a deep-seated change in both technology and its application. Any institutions in our day anticipate to get more value from their investments in technology. In the “Post dearth era of calculation” the user-friendliness of dispensation power is not a check where cost of platform technology has become a minor bourgeois in selecting among alternatives to build the business solution and as such the constraining factors are the managerial impact of reengineering the business process and the costs and time required for system development. Additionally, the need to re-educate organisation to the compulsory level of expertise can be an extremely costly scheme. Open systems enable organizations to purchase off-the-shelf solutions to business problems. Open systems standards set apart the design in which data is swapped, remote systems are accessed, and services are attracted. The receipt of open systems standards supports the creation of system architectures that can be built from technology components. These standards enable us, as follows:
• To build reusable class libraries to use in object-oriented design and development environments.
• To build functional products those interact with the same data which are bedded on goal oriented as well as bedded on full integrity.
• To alter a correspondence at an individual desktop workstation to include data, addressing and graphics input from a word processor, a individualized spreadsheet, a workgroup database, and an existing project host relevance to be propelled by electronic mail to someplace in the world.
It is worth mentioning that opposing to the claims of groups variety from the Open Software base to the individual consortium Open User Suggested Solutions, open systems are not exclusively systems that conform to OSF UNIX specifications. The client/server model makes the enterprise acquirable at the desk. It provides access to data that the previous architectures did not. Standards have been defined for client-server figuring. If these principles are understood and used, a society can rationally anticipate to purchase solutions this day that can grow with their business needs without the constant need to revise the solutions. Architectures based on open systems standards can be implemented throughout the world, as global systems become the norm for massive organizations. While a supportable common platform on a global scale is far from standardized, it certainly is becoming much easier to accomplish. From the desktop, enterprise-wide applications are indistinguishable from workgroup and individualized applications. Powerful enabling technologies with built-in conformance to open systems standards are evolving rapidly. Examples include object-oriented development, relational and object-oriented databases, multimedia, imaging, expert systems, geographic information systems, voice recognition and voice response, and text management. These technologies wage the opportunity to integrate their generic potential—with the particular necessities of a business—to create a cost-effective and personalized business solution. The client/server model provides the saint platform with which to integrate these enabling technologies. Well-defined interface standards enable integration of products from several vendors to wage the right application solution. Enterprise systems are those that create and wage a shared information resource for the entire corporation. They do not imply centralized development and control, but they do treat information and technology as corporate resources. Enterprise network management requires all devices and applications in the enterprise computing environment to be visible and managed. This remains a major challenge as organizations move to distributed processing. Standards are defined and are being implemented within the client/server model. Client/server applications give greater viability to worker empowerment in a distributed organization than do today’s host-centered environments.
Prospects are accessible to society and populace who are equipped and capable to compete in the global market and there is no denying the fact that a competitive global economy will ensure obsolescence and incomprehensibility to those who can't or are unwilling to compete. All organizations must look for ways to demonstrate value. We are in conclusion bearing in mind that an enthusiasm has to rethink upon existing managerial structures and commerce in putting into practice. Organizations are aggressively downsizing even as they try to aggressively expand their revenue base. There is more willingness to continue improvement practices and programs to eliminate redundancy and increase effectiveness. Organizations are becoming market-driven while remaining true to their business vision. To be competitive in a global economy, organizations in developed economies must employ technology to acquire the efficiencies necessary to offset their higher fag costs. Reengineering the business process to wage information and decision-making support at points of customer contact reduces the need for layers of decision-making management, improves responsiveness, and enhances customer service. Empowerment means that knowledge and responsibility are acquirable to the employee at the point of customer contact. Empowerment will ensure that product and service problems and opportunities are identified and finalized. Client/server computing is the most effective source for the tools that empower employees with dominance and responsibility. The following are some key drivers in organizational philosophy, policies, and practices. Competitiveness is forcing organizations to find new ways to manage their business, despite fewer personnel, more outsourcing, a market-driven orientation, and rapid product obsolescence. Technology can be the enabler of organizational nimbleness. To survive and prosper in a world where trade barriers are being eliminated, organizations must look for partnerships and processes that are not restrained by artificial borders. Quality, cost, product differentiation, and service are the new marketing priorities. Our information systems must support these priorities.
Contesting demands that information systems organizations justify their costs and it is evident that business are in the way to question the return on their existing investments and as such Centralized IS an operation in particular are under the microscope. Manufactured goods obsolescence has never been so vital a factor. Purchasers have more options and are more demanding. Technology must enable organizations to anticipate demand and meet it. Quality and flexibility require decisions to be prefabricated by individuals who are in touch with the customer. Many organizations are eliminating layers of middle management. Technology must wage the necessary information and support to this new structure. If a business is run from its distributed locations, the technology supporting these units must be as reliable as the existing central systems. Technology for remote management of the distributed technology is essential in order to use scarce expertise appropriately and to reduce costs. Each individual must have access to all information he or she has a “need and right” to access, without regard to where it is collected, determined, or located. We can use technology this day to wage this “single-system image” of information at the desk, whatever the technology used to create it. Standardization has introduced many new suppliers and has dramatically reduced costs. Competition is driving innovation. Organizations must use architectures that take advantage of cost-effective offerings as they appear. Desktop workstations now wage the power and mainframe capacity that mainframes did only a few years ago. The challenge is to effectively use this power and capacity to create solutions to real business problems. Downsizing and empowerment require that the workgroup have access to information and work collectively. Decisions are being prefabricated in the workplace, not in the head office. Standards and new technologies enable workstation users to access information and systems without regard to location. Remote network management enables experts to wage support and central, system-like reliability to distributed systems. However, distributed systems are not transparent. Data access crossways a network often has unpredictable result sets; therefore, performance on existing networks is often inadequate, requiring a retooling of the existing network infrastructure to support the new data access environment.
Standards enable many new vendors to enter the market. With a common platform target, apiece product has the entire marketplace as a potential customer. With the high rate of introduction of products, it is certain that organizations will have to deal with multiple vendors. Only through a commitment to standards-based technology will the heterogeneous multiple vendor environment effectively service the buyer. Workstation power, workgroup empowerment, preservation of existing investments, remote network management, and market-driven business are the forces creating the need for client/server computing. The technology is here; what is missing is the expertise to effectively apply it. Organizational pressures to demonstrate value apply as much to the information systems functions as to any other element or operating unit of the business. This is a special challenge because most IS organizations have not previously experienced strong financial constraints, nor have they been measured for success using the same business justification “yardstick” as other value-creating units within the business enterprise. IS has not been under the microscope to establish that the role it plays truly adds value to the overall organization. In today’s world, organizations that can't be seen to add value are either eliminated or outsourced. It has been found out on a survey that about 1000 companies, on average, spend 90 percent of IS dollars maintaining existing systems. Major business benefits, however, are acquirable only from “new” systems. Dramatic reductions in the cost of technology help cost justify many systems. Organizations that adapt faster than their competitors demonstrate value and become the leaders in their marketplace. Products and services command a premium price when these organizations are “early to market.” As they become commodities, they attract only commodity prices. This is true of both commercial organizations wishing to be competitive in the market with their products and of service organizations wishing to demonstrate value within their department or government sector. “It only took God seven days to create the world because he didn’t have an existing environment to deal with.”3 Billions of dollars have been invested in corporate computing infrastructure and training. This investment must be fully used. Successful client/server solutions integrate with the existing applications and wage a gradual migration to the new platforms and business models.
To meet the goals of the 1990s, organizations are downsizing and eliminating middle-management positions. They want to transfer responsibility to empower the mortal closest to the customer to make decisions. Historically, individualized systems have imposed the burden of data collection and maintenance on the front-line work force but have husbanded information in the head office to support decision making by middle management. Information must be prefabricated acquirable to the data creators and maintainers by providing the connectivity and distributed management of enterprise databases and applications. The technology of client/server computing will support the movement of information processing to the direct creators and users of information. OLTP applications traditionally have been used in insurance, financial, government, and sales-related organizations. These applications are characterized by their need for highly reliable platforms that guarantee that transactions will be handled correctly, no data will be lost, and response times will be extremely low, and only authorized users will have access to an application. The IS industry comprehends OLTP in the traditional mainframe-centered platforms but not in the distributed client/server platforms. Organizations do (and will continue) to rely on technology to drive business. Much of the IS industry does not yet comprehend how to build mission-critical applications on client/server platforms. As organizations move to employee empowerment and workgroup computing, the desktop becomes the critical technology element running the business. Client/server applications and platforms must wage mainframe levels of reliability. Executive information systems wage a single-screen view of “how well we are doing” by comparing the mass of details contained in their current and historical enterprise databases with information obtained from outside sources about the economy and competition. As organizations enter into corporation with their customers and suppliers, the need to integrate with external systems becomes essential in order to capture the necessary information for an effective EIS. Organizations want to use the EIS data to make strategic decisions. The DSS should wage “what if” analyses to project the results of these decisions. Managers define expectations, and the local processing ability generates decision alerts when reality does not conform. This is the DSS of the client/server model. Information is now recognized as a corporate resource. To be truly effective, organizations must collect data at the source and distribute it, according to the stipulations of “need and right to access,” throughout the organization. Workgroups will choose the platforms that saint meet their needs, and these platforms must integrate to support the enterprise solution. Systems built around open systems standards are essential for cost-effective integration. Los Angeles County issued a request for information stating simply that its goal was “to implement and operate a modern telecommunications network that creates a seamless utility for all County telecommunications applications from desktop to desktop. The United Says government has initiated a project—the National Information Interchange that has the simple neutral of “making the intellectual property of the United Says acquirable to all with a need and right to access.
“Computers will become a truly useful part of our society only when they are linked by an infrastructure like the highway system and the electric power grid, creating a new kind of free market for information services. The feature that makes the highway and electric power grids truly useful is their pervasiveness. Each home and office has ready access to these services; thus, they are used—without thought—in the normal course of living and working. This pervasive accessibility has emerged largely because of the adoption of standards for interconnection. If there were no standards for driving, envision the confusion and danger. What if apiece surround plug were a different shape, or the power acquirable on apiece plug were random? If using a service requires too much thought and attention, that service can't become a default part of our living and working environment. “Imagine the United Says without its highways. Our millions of cars, buses, and trucks driven in our own backyards and neighborhood parking lots, with occasional forays by the daring few along uncharted, unpredictable, and treacherous dirt roads, full of unspeakable terrors.”7 The parking lot analogy illustrated in Figure 1.1 represents the current information-processing environment in most organizations. It is simple and transparent to locate and use information on a local area network (LAN), but information located on another LAN is nearly inaccessible. End-user access to enterprise data often is unavailable except for predefined information requests. Even though computers—from mainframes to PCs—are numerous, powerful, flexible, and widely used, they are still used in relative isolation. When they communicate, they usually do so ineffectively, through arcane and arbitrary procedures. Information comes with many faces. As shown in Figure 1.2, it can take the form of text, drawings, music, speech, photographs, stock prices, invoices, software, live video, and many other entities. Yet once information is computerized, it becomes a deceptively uniform sequence of ones and zeros. The underlying infrastructure must be flexible in the way it transports these ones and zeros. To be truly effective besides routing these binaries to their destinations the infrastructure must be healthy to carry binaries with varying degrees of speed, accuracy, and security to accommodate different individualized abilities and needs.
Because individualized are manufactured and sold by vendors with differing views on the most effective technology, they do not share common implementation concepts. Transporting ones and zeros around, however flexibly, isn’t enough. Personal based on different technologies can't comprehend apiece other’s ones and zeros any more than people comprehend foreign languages. We therefore need to endow our IS organizations with a set of widely understood common information interchange conventions. Moreover, these conventions must be based on concepts that make life easier for humans, rather than for individualized servants. Finally, the truly useful infrastructure must be equipped with “common servers”—computers that wage a few basic information services of wide interest, such as computerized white and yellow pages.

Technological innovation proceeds at a pace that challenges the human mind to comprehend how to take advantage of its capabilities. Electronic information management, technological innovation in the individualized computer, high-speed electronic communication, and digital encoding of information wage new opportunities for enhanced services at lower cost. Personal individualized can wage services directly to people who have minimal individualized experience. They wage low-cost, high-performance computing engines at the site that the individual lives, works, or accesses the service—regardless of where the information is physically stored. Standards for individual interface, data access, and intercrosses communications have been defined for the individualized individualized and are being adopted by a majority of the vendor community. There is no reason to accept solutions that do not conform to the accepted standards. Most massive organizations this day use a heterogeneous collection of hardware, software, and connectivity technologies. There is considerable momentum toward increased use of technology from multiple vendors. This trend leads to an increasingly heterogeneous environment for users and developers of individualized systems. Users are interested in the business functionality, not the technology. Developers rarely are interested in more than a subset of the technology. The concept of the single-system image states that you can build systems that wage transparency of the technology platform to the individual and—at the largest extent possible—to the developer. Developers will need adequate knowledge of the syntax used to solve the business problem, but will need tiny or no knowledge of the underlying technology infrastructure. Hardware platforms, operating systems, database engines, and communications protocols are necessary technological components of any individualized solution, but they should wage services—not create obstacles to getting the job done. Services should be masked; that is, they should be provided in a natural manner without requiring the individual to make unnatural gyrations to invoke them. Only by masking these services and by using standard interfaces can we hope to develop systems swiftly and economically. At the same time, masking (known as encapsulation in object-oriented programming) and standard interfaces preserve the ability to change the underlying technology without affecting the application. There is value in restricting imagination when you build system architectures. Systems development is not an art; it is an engineering discipline that can be learned and used. Systems can be built on the foundations established by previous projects.
Within the single-system image environment, a business system individual is absolutely unaware of where data is stored, how the client and server processors work, and what networking is involved in gaining connectivity. Each application that the individual accesses provides a common “look and feel.” Help is provided in the same way by apiece application. Errors are presented and resolved in the same way by apiece application. Access is provided through a standard security procedure for apiece application. Each individual has access to all services for which he or she has a need and a right to access.
• The security layer is invisible to the authorized and impenetrable to the unauthorized.
• Navigation from function to function and application to application is provided in the same way in apiece system. New applications can be added with minimal training, because the standard functions work in the same way, and only the new business functions need be learned. It is not necessary to go to “boot camp for basic training” prior to using apiece new application. Basic training is a one-time effort because the basics do not change.
The complexity of a heterogeneous computing platform will result in many interfaces at both the logical and physical level. Organizations evolve from one platform to another as the industry changes, as new technologies evolve that are more cost effective, and as acquisitions and mergers introduce other installed platforms. All these advances must be accommodated. There is complexity and risk when attempting to interoperate among technologies from many vendors. It is necessary to engage in “proof of concept” testing to distinguish the marketing version of products and architectures from the delivered version. Many organizations use a test work concept called technology competency centers to do this “proof of concept.” The TCC concept provides a local, small-scale model of all the technologies involved in a potential single-system, interoperable image. Installing a proposed solution using a TCC is a low-cost means of ensuring that the solution is viable. These labs enable rapid installation of the proposed solution into a proven environment. They eliminate the need to set up from scratch all the components that are necessary to support the one-of-a-kind part of a new application. Organizations—Merrill Lynch, Health Canada, SHL System house, BSG Corporation, Microsoft, and many others—use such labs to do sanity checks on new technologies. The rapid changes in technology ability dictate that such a resource be acquirable to validate new products. The single-system image is saint implemented through the client/server model.. Our experience confirms that client/server computing can wage the enterprise to the desktop. Because the desktop individualized is the user’s view into the enterprise, there is no superior way to guarantee a single image than to begin at the desktop. Unfortunately, it often seems as if the number of definitions of client/server computing depends on how many organizations you survey, whether they’re hardware and software vendors, integrators, or IS groups. Each has a vested interest in a definition that makes its particular product or service an indispensable component. Throughout this book, the following definitions will be used consistently:
• Client: A client is a single-user workstation that provides presentation services and the appropriate computing, connectivity, and database services and interfaces relevant to the business need.
• Server: A server is one or more multi-user processors with shared memory providing computing, connectivity, and database services and interfaces relevant to the business need.
Client/server computing is an environment that satisfies the business need by appropriately allocating the application processing between the client and the server processors. The client requests services from the server; the server processes the request and returns the result to the client. The communications mechanism is a message passing interposes communication (IPC) that enables (but does not require) distributed placement of the client and server processes. Client/server is a software model of computing, not a hardware definition. This definition makes client/server a rather generic model and fits what is known in the industry as “cooperative processing” or “peer-to-peer.” Because the client/server environment is typically heterogeneous, the hardware platform and operating system of the client and server are not usually the same. In such cases, the communications mechanism might be further extended through a well-defined set of standard application program interfaces (APIs) and remote procedure calls. The modern diagram representing the client/server model was probably first popularized by Sybase. Figure 1.4 illustrates the single-system image vision. A client-user relies on the desktop workstation for all computing needs. Whether the application runs absolutely on the desktop or uses services provided by one or more servers—be they powerful computers or mainframes—is irrelevant. Effective client/server computing will be fundamentally platform-independent. The individual of an application wants the business functionality it provides; the computing platform provides access to this business functionality. There is no benefit, yet considerable risk, in exposing this platform to its user. Changes in platform and underlying technology should be transparent to the user. Training costs, business processing delays and errors, staff frustration, and staff turnover result from the confusion generated by changes in environments where the individual is sensitive to the technology platform.

It is easily demonstrated that systems built with transparency to the technology, for all users, offer the highest probability of solid ongoing return for the technology investment. It is equally demonstrable that if developers become aware of the target platform, development will be bound to that platform. Developers will use special features, tricks, and syntax found only in the specific development platform. Tools, which isolate developers from the specifics of any single platform, assist developers in writing transparent, portable applications. These tools must be acquirable for apiece of the three essential components in any application: data access, processing, and interfaces. Data access includes the graphical individual interface (GUI) and stored data access. Processing includes the business logic. Interfaces link services with other applications. This simple model, reflected in Figure 1.5, should be kept in mind when following the evolution to client/server computing. The use of technology layers provides this application development isolation. These layers isolate the characteristics of the technology at apiece level from the layer above and below. This layering is fundamental to the development of applications in the client/server model. The rapid rate of change in these technologies and the demand of experience with the “best” solutions implies that we must isolate specific technologies from apiece other. This book will continue to accentuate and expand on the concept of a systems development environment (SDE) as a way to achieve this isolation. Developer tools are by far the most visible. Most developers need to know only the syntax of these tools to express the business problem in a format acceptable to the technology platform. With the increasing involvement of minicomputer professionals, as technology users and application assemblers, technology isolation is even more important. Very few—perhaps none—of an organization’s application development staff needs to be aware of the hardware, system software, specific database engines, specific communications products, or specific presentation services products. These are invoked through the APIs message passing, and generated by tools or by a few technical specialists. As you will see in Chapter 6, the development of an application structure supported by a technical structure and systems development environment is the key to achieving this platform independence and finally to developing successful client/server applications.
As organizations increase the use of individualized productivity tools, workstations become widely installed. The need to protect desktop real estate requires that host terminal abilities be provided by the single workstation. It soon becomes evident that the power of the workstation is not being tapped and application processing migrates to the desktop. Once most users are connected from their workstation desktop to the applications and data at the host mainframe or minicomputer, there is significant cost benefit in offloading processing to these powerful workstations. The first applications tend to be data capture and edit. These simplify—but still use—the transaction expected by an already existing host application. If the workstation is to become truly integrated with the application, reengineering of the business process will be necessary. Bookkeeping functions and many customer service applications are easily offloaded in this manner. Thus, workgroup and departmental processing is done at the LAN level, with host involvement for enterprise-wide data and enforcement of interdepartmental business rules. In this “dumb” terminal (IBM uses the euphemism nonprogrammable to describe its 327x devices) emulation environment, all application logic resides in the minicomputer, mainframe, or workstation. Clearly a 00 or less desktop workstation is capable of much more than the character display provided by a 0 terminal. In the client/server model, the low-cost processing power of the workstation will replace host processing, and the application logic will be divided appropriately among the platforms. As previously noted, this distribution of function and data is transparent to the individual and application developer.
The mainframe-centric model uses the presentation abilities of the workstation to front-end existing applications. The character mode interface is remapped by products such as Easel and Mozart. The same data is displayed or entered through the use of pull-down lists, scrollable fields, check boxes, and buttons; the individual interface is simple to use, and information is presented more clearly. In this mainframe-centric model, mainframe applications continue to run unmodified, because the existing terminal data stream is processed by the workstation-based communications API. This protects the investment in existing applications while improving performance and reducing costs. Character mode applications, usually driven from a block mode screen, attempt to display as much data as doable in order to reduce the number of transmissions required to complete a function. Dumb terminals impose limitations on the individual interface including fixed length fields, fixed length lists, crowded screens, single or limited character fonts, limited or no graphics icons, and limited windowing for multiple application display. In addition, the fixed layout of the screen makes it difficult to support the display of conditionally derived information. In contrast, the workstation GUI provides facilities to build the screen dynamically. This enables screens to be built with a variable format based conditionally on the data values of specific fields. Variable length fields can be scrollable, and lists of fields can have a scrollable number of rows. This enables a much larger virtual screen to be used with no additional data communicated between the client workstation and server. Windowing can be used to pull up additional information such as help text, valid value lists, and error messages without losing the original screen contents. The more robust GUI facilities of the workstation enable the individual to navigate easily around the screen. Additional information can be encapsulated by varying the display’s colors, fonts, graphics icons, scrollable lists, pull-down lists, and option boxes. Option lists can be provided to enable users to swiftly choose input values. Help can be provided, based on the context and the cursor location, using the same pull-down list facilities. Even though it is a limited use of client/server computing capability, a GUI front end to an existing application is frequently the first client/server-like application implemented by organizations familiar with the host mainframe and dumb-terminal approach. The GUI preserves the existing investment while providing the benefits of assist of use associated with a GUI. It is doable to wage dramatic and functionally rich changes to the individual interface without host application change.
The next logical step is the supplying of some edit and processing logic executing at the desktop workstation. This additional logic can be added without requiring changes in the host application and might reduce the host transaction rate by sending up only valid transactions. With minimal changes to the host application, network traffic can be reduced and performance can be improved by using the workstation’s processing power to encode the data stream into a compressed form. A more interactive individual interface can be provided with built-in, context-sensitive help, and extensive prompting and individual interfaces that are sensitive to the users’ level of expertise. These options can be added through the use of workstation processing power. These abilities enable users to operate an existing system with less intensive training and might even wage the opportunity for public access to the applications. Electronic data interchange (EDI) is an example of this front-end processing. EDI enables organizations to communicate electronically with their suppliers or customers. Frequently, these systems wage the workstation front end to deal with the EDI link but continue to work with the existing back-end host system applications. Messages are reformatted and responses are handled by the EDI client, but application processing is done by the existing application server. Productivity might be enhanced significantly by capturing information at the source and making it acquirable to all authorized users. Typically, if users employ a multipart form for data capture, the form data is entered into multiple systems. Capturing this information once to a server in a client/server application, and reusing the data for several client applications can reduce errors, lower data entry costs, and speed up the availability of this information.
There is no delay while the forms are passed around the organization. This is usually a superior technique than forms imaging technology in which the forms are created and distributed internally in an organization. The use of workflow-management technology and techniques, in conjunction with imaging technology, is an effective way of handling this process when forms are filled out by a mortal who is physically remote from the organization. Intelligent Character Recognition (ICR) technology can be an extremely effective way to automate the capture of data from a form, without the need to key. Current experience with this technique shows accuracy rates greater than 99.5 percent for typed forms and greater than 98.5 percent for handwritten forms.

Rightsizing and rationalizing are strategies used with the client/server model to take advantage of the lower cost of workstation technology. Rightsizing and upsizing might involve the addition of more diverse or more powerful computing resources to an enterprise computing environment. The benefits of rightsizing are reduction in cost and/or increased functionality, performance, and flexibility in the applications of the enterprise. Significant cost savings usually are obtained from a resulting reduction in employee, hardware, software, and maintenance expenses. Additional savings typically accrue from the improved effectiveness of the individual community using client/server technology. Eliminating middle layers of management implies empowerment to the first level of management with the decision-making dominance for the whole job. Information provided at the desktop by networked computers and workstations integrated with existing host (such as mainframe and minicomputer) applications is necessary to assist this empowerment. These desktop-host integrated systems home the information required to make decisions quickly. To be effective, the desktop workstation must wage access to this information as part of the normal business practice. Architects and developers must work closely with business decision makers to ensure that new applications and systems are designed to be integrated with effective business processes. Much of the cause of poor return on technology investment is attributable to a demand of understanding by the designers of the day-to-day business impact of their solutions. Downsizing information systems is more than an attempt to use cheaper workstation technologies to replace existing mainframes and minicomputers in use. Even though some benefit is obtained by this approach, greater benefit is obtained by reengineering the business processes to really use the abilities of the desktop environment. Systems solutions are effective only when they are seen by the actual individual to add value to the business process. Client/server technology implemented on low-cost standard hardware will drive downsizing. Client/server computing makes the desktop the users’ enterprise. As we move from the machine-centered era of computing into the workgroup era, the desktop workstation is empowering the business individual to regain ownership of his or her information resource. Client/server computing combines the saint of the old with the new—the reliable multi-user access to shared data and resources with the intuitive, powerful desktop workstation.
In view of the above it is evident that object-oriented development concepts are embodied in the use of an SDE created for an organization from an architecturally selected set of tools. The SDE provides more effective development and maintenance than companies have experienced with traditional host-based approaches. Client/server computing is open computing. Mix and match is the rule. Development tools and development environments must be created with both openness and standards in mind. Mainframe applications rarely can be downsized—without modifications—to a workstation environment. Modifications can be minor, wherein tools are used to port existing mainframe source code—or major, wherein the applications are rewritten using absolutely new tools. In porting, native COBOL compilers, functional file systems, and emulators for DB2, IMS DB/DC, and CICS are acquirable for workstations. In rewriting, there is a broad array of tools ranging from PowerBuilder, Visual Basic, and Access, to larger scale tools such as Forte and Dynasty. Micro Focus has added an Object Oriented (OO) option to its workbench to assist the creation of reusable components. The OO option supports integration with applications developed under Smalltalk/V PM. IBM’s CICS for OS/2, OS400, RS6000, and HP/UX products enable developers to directly port applications using standard CICS call interfaces from the mainframe to the workstation. These applications can then run under OS/2, AIX, OS400, HP/UX, or MVS/VSE without modification. This promises to enable developers to create applications for execution in the CICS MVS environment and later to port them to these other environments without modification. Conversely, applications can be designed and built for such environments and subsequently ported to MVS (if this is a logical move). Organizations envisioning such a migration should ensure that their SDE incorporates standards that are consistent for all of these platforms.
These harvests, pooled with the economical processing power acquirable on the workstation, make the workstation Local Area Network an saint expansion and maintenance environment for existing host processors. When an organization views mainframe or minicomputer resources as real dollars, developers can usually justify offloading the development in only three to six months. Explorers can be effective only when a proper systems development environment is place in place and provided with a suite of tools offering the host abilities plus enhanced connectivity. Workstation operating systems are still more primitive than the existing host server MVS, VMS, or UNIX operating systems. Therefore, appropriate standards and procedures must be place in place to coordinate shared development. The workstation environment will change. Only projects built with common standards and procedures will be resilient enough to remain viable in the new environment.
The major reserves come up to from new projects that can create apposite values at the initiate and do all development using the workstation LAN environment. It is doable to retrofit standards to an existing environment and establish a workstation with a LAN-based maintenance environment. The benefits are less because retrofitting the standards creates some costs. However, these costs are justified when the application is scheduled to undergo significant maintenance or if the application is very critical and there is a desire to reduce the error rate created by changes. The discipline associated with the movement toward client/server-based development, and the transfer of code between the host and client/server will nearly certainly result in superior testing and fewer errors. The testing facilities and usability of the workstation will make the developer and tester more effective and therefore more accurate. Business processes use database, communications, and application services. In an saint world, we pick the saint servers acquirable to wage these services, thereby enabling our organizations to enjoy the maximum benefit that current technology provides. Real-world developers’ make compromises around the existing technology, existing application products, training investments, product support, and a myriad other factors. Key to the success of full client/server applications is selecting an appropriate application and technical structure for the organization. Once the technical structure is defined, the tools are known.
The eventual pace is to accomplish an SDE to categorize the principles desirable to use the tools in actual fact. This SDE is the collection of hardware, software, standards, standard procedures, interfaces, and training built up to support the organization’s particular needs. Many construction projects change because their developers adopt that a mortal with a toolbox full of carpenter’s tools is a capable builder.

In view of the above, it is evident that in order to be a successful planner, a mortal needs be trained to build according to standards. The creation of standards to define interfaces to the sewerage, water, electrical utilities, road, school, and community systems is essential for successful, cost-effective building. We do not anticipate a carpenter to design such interfaces individually for apiece building. Rather, pragmatism discourages imagination in this regard. By reusing the models previously built to accomplish integration, we all benefit from cost and risk reduction. Suffice it to state that the preamble of a whole new generation of Object oriented Technology based on tools for client/server development demands that proper standards can be place in place to support shared development, reusable code, interfaces to existing systems, security, error handling, and an organizational standard “gaze and think.” As with any new technology, there will be changes. Developers can build application systems closely tied to today’s technology or use an SDE and promote applications that can progress along with the expertise podium.

How Information Database Systems Work

Thu, 10 Feb 2011 17:55:27 +0000

The storage of files into a common representational pool is the function of databases, they utilize various classification models relative to the type of content involved, and these include relational model, database model, the hierarchical model and the network model.

The Online Transaction Processing (OLTP) systems make use of the goal oriented data store structure or row oriented, while the DBMS structure is column oriented and is usually employed by retrieval focused applications such as the data warehouse and the bibliographic database systems.

Databases can make use of variety of strategies, and they incorporate software based containers designed to collect and store information, in a way that enables users to easily update, retrieve and remove information.

Flexible databases otherwise known as general purpose database systems have enjoyed widespread usage due to their capacity to handle an extensive range of data processing functions.

They derive their flexibility from the enhancements prefabricated to their extensible data types, this translates to allowances for the development of a variety of applications.

The goal database management handles its storage functions without translating into a distinct storage schema or making use of separate definition language. Whereas the relational systems store the connections between complex data types as part of their storage model, without the necessity for runtime calculation using relational algebra execution algorithms.

The database management system (DBMS) comes with a software that assists in the organization of data, this system takes charge of the use, maintenance and use of the database storage structures. And often start into the database model they support like the object, relational or network model.

These models usually dictate the query language that are used to access the database, the goal database commonly uses the OQL while the relational model employs the SQL.

Some database play a pivotal in the operations of productive organizations, and they store detailed information needed on day to day basis and they can follow under customer databases, individualized databases or inventory databases along the lines of umbrella versions such as production databases, transaction and subject area databases (SADB).

The data warehouses are responsible for what can be termed as data archiving, it combines data from different operational databases of an organization to form a central source of screened, edited integrated and standard data, spanning long periods of time. While analytical databases also stores information from various operational databases, and it includes summarized data and some information relevant to the organization’s management and general operations.

Information technology and clinical technology

Sun, 30 Jan 2011 00:06:30 +0000

Health Technology & COMPUTER disruptive in clinical care

Basically strategies and targets on the HIT program is the foundation underlying all other processes. Firstly, to inform all stakeholders on the use of clinical systems decision support in clinical operations is very important, which reduces the drug dosage errors. In addition, the introduction of electronic patient records in all health centers to be prefabricated compulsory. This is so because, high calibre and medicines shall be, so to help promote the health of the patent. Adoption of information technology is also the calibre of patient care. The removal of all barriers to the adoption of HIT should be performed. First, the mobilization of financial resources adequate to ensure full implementation of the process is essential. Empowering staff with knowledge and skills on the use of information technology and more if the computer. Another point of concern in the adoption of HIT is the issue of confidentiality. With all the health centers, the issue of confidentiality, which makes it useful HIT (Davis, 2002)

priority in clinical care, future developments and technological innovations are likely to witness. Despite his immense disruption to existing technologies, they can develop substantial benefits for health care. First, one of the most important for the future disruptive technologies in the healthcare system acre, the use of technology-based diagnostic and therapeutic procedures. This is an innovation and doable developments that can cause a lot of benefits in addition to disrupting the existing methods of diagnosis. It should be noted that the new technology breakthrough in the diagnosis of patients might be less invasive, or even cost compared to technologies that will replace them. One point that deserves consideration s that the cost will be for the new technologies required by high short-term training of staff and perhaps plants. Nevertheless, the benefits outweigh the costs in all cases because of the calibre and efficiency gained in the process (Ian, 2000).

Another disruptive technology of the future in clinical care include the introduction of electronic medical records (EMR), clinical data repositories will be linked. In addition, the systems created new neural networks and expert systems to the system and time information. This can be a great development in clinical care, as it will help improve the doctor to diagnose vision. On the basis of future development, the costs can be very high n the opening process. This is so because it will make existing technology obsolete, and the high cost of acquiring new plants and equipment. In addition, the cost of training of human power, but also quite high in the short period since it requires the restructuring of the entire system. Fortunately, many benefits of future technologies will be implemented, the calibre and effectiveness of drug administration to increase (Ian, 2000).

Significantly, the adoption of e-mail and World wide web secure portal to assist communication in clinical care could be a disruptive technology of the future. This will ensure the assist and efficiency of communication between the patients with whom they can enter appointments, request prescription refills obtained, the results of work and imaging study and report data self-monitoring. When you use secure World wide web portal and e-mail to patients for their own medical records and other calls to make in terms of their health. On the basis of this innovation will be noncurrent future of existing technology for communication and access to records. Despite the high cost of implementation, the benefits of this technology are enormous. Indeed, confidentiality, effectiveness and cost of treatment of patient records and information must be facilitated.
