Most information systems managers have three goals: to purchase technology that actually provides the features and functions the vendor says it possesses, to select the proper new technology and to keep within their budget when purchasing the new technology. Initially, technology should be evaluated before making a tentative commitment. Peers who are in the process of, or who already have implemented the same technology should be asked for feedback about the product. They should also be asked if the technology went the long haul, or if they encountered problems, and how helpful the vendor was in getting the problems straightened out. Consultants can also be asked about products, but resellers of the product should be avoided as they have lost their objectivity. After a few products have been weeded out, the next step is prototyping, and can be of help in convincing upper management of the necessity in changing technology. The new technology should be introduced a little bit at a time, keeping long-term goals in mind.
Relational data bases and relational-like fourth-generation software are useful for many applications, including electronic file cabinet systems, decision support systems, user-friendly systems that must be quickly constructed and changed, and prototyping. But they are not a panacea. Because they consume a lot of hardware resources, they are ineffective for on-line operational processing. After implementing a relational system, one company reported a fifty percent annual increase in the hardware budget over a five year period.

Nonprocedural Languages, Study, User Relations, Evaluation, Programming, Programming Language, and Application Development Software
According to Input Inc.'s report titled Opportunities of Fourth-Generation Languages, fourth-generation languages can solve several problems relating to information systems. These problems include isolation of information systems from the rest of the organization; the development of systems that are late, incomplete, or inflexible; the perception of the information systems department as unresponsive; and user ignorance of data processing functions. The report predicts fourth-generation languages will play an important role in the systems development process. In addition, micro versions will offer some attractive options, including micro-mainframe communication and prototyping.

Evaluation, Software Packages, Prototype, Application Development Software, Applications Programming, Software Garden Inc., and Demo II (Program development software)
The Demo II prototyping program for developing microcomputer-based applications is a brilliant example of how a start-up firm with no resources except good ideas can produce an imaginative, practical, and very successful product. The $195 program is both powerful and easy to use in creating a realistic interaction between the user and the hypothetical prototype system. The idea behind Demo II is of screen images that are linked to simulate an application's screen, including text, lines, boxes, menus, and graphics displays. A powerful overlay facility allows screen images to be made from standard templates that are changed to any degree desired. Enhancements in the new version are: handling of bit-mapped images; support for IBM EGA and VGA; and several new command actions. Documentation is outstanding. Demo II is indispensable for PC applications development.
