GraphiText's successor product, DesignAid was the first microprocessor-based tool to logically and semantically evaluate software and system design diagrams and build a data dictionary.
While, at the time of launch, and for several years, the IBM platform did not support networking or a centralized database as did the Convergent Technologies or Burroughs machines, the allure of IBM was strong, and Excelerator came to prominence.
The goal of introducing CASE tools is the reduction of the time and cost of software development and the enhancement of the quality of the systems developed. The interest in CASE tools and environments is based on expectations about increasing productivity, improving product quality, facilitating maintenance, and making software engineers' task less odious and more enjoyable.
CASE is the use of computer-based support in the software development process; a CASE tool is a computer-based product aimed at supporting one or more software engineering activities within a software development process; a CASE environment is a collection of CASE tools and other components together with an integration approach that supports most or all of the interactions that occur among the environment components, and between the users of the environment and the environment itself.
Many prior studies have reported limited use of CASE tools. In a survey of 53 companies, found that 39 Of the 14 companies who had tried CASE, five had subsequently abandoned use of the tools.
People within these fourteen companies believed that use of CASE tools improved documentation quality, improved analysis, and resulted in systems that were easier to test and maintain. However, they also found use of CASE tools difficult and time consuming. In a follow-up survey of thirteen managers who had been using CASE tools two years earlier, reported that continued CASE use could only be verified for four managers.
The reasons for abandonment included cost, lack of measurable turns, and unrealistic expectations. When the term CASE is used, it is important to clarify what is being discussed.
An upper CASE tool front end CASE provides support for the early stages in the systems development life cycle such as requirements analysis and design. Integrated CASE tools support both the early and later stages. Further classifications usually list which functionalities are supported by the tool, such as data flow diagrams, entity relationships data models, etc. CASE Tools offer an excellent array of features that support the development and business community through its Automated Diagram Support feature.
The various popular features that aid the development community are listed below:. CASE technology is the automation of step by step methodologies for software and system development. CASE tools are characterized by the stage or stages of software development life cycle on which they focus. Since different tools covering different stages share common information, it is required that they integrate through some central repository system data dictionary to have a consistent view of such information.
In phases of software development life cycle integrated through a central data dictionary. Case Tools are used in many ways in our organizations. Case tools can be broadly classed into these broader areas:. While many organizations still use the SDLC methodology, it is often supplemented with other methods. They mainly use it while developing the following methodologies:. If you are already a software engineer, consider expanding your knowledge of CASE tools through continuing education to broaden your job prospects.
There are many different types of CASE tools, all of which can serve different purposes, so it may be a good idea for software engineers to become familiar with the variety and the benefits of each.
Additionally, CASE tools are continually being developed, becoming more readily available, affordable, and more capable. Continuing education can help you keep on top of these developments. As software engineering becomes more and more complex, and businesses seeking to be as cost-efficient as possible, the need for CASE tool knowledge, complex in itself, will continue to be important. Many studies have been done on the use of CASE tools, and the results point to their benefit but with the importance of correct use by a strong software developer.
In other words, they do not ensure that anyone can write a good computer system, but they enable experienced software developers to do an even better job. So, if you are interested or already working in software engineering, consider extending your educational path to cover CASE tools, and you will likely become even more marketable as a software engineer.
