STUDY OF USE CASE TOOL
HISTORY:
The term CASE was originally coined by software company, Nastec Corporation of Southfield, Michigan in 1982 with their original integrated graphics and text editor Graphite, which also was the first microcomputer-based system to use hyperlinks to cross-reference text strings in documents — an early forerunner of today's web page link. 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. The next entrant into the market was Excelerator from Index Technology in Cambridge, Mass. While DesignAid ran on Convergent Technologies and later Burroughs Ngen networked microcomputers, Index launched Excelerator on the IBM PC/AT platform. 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. Hot on the heels of Excelerator were a rash of offerings from companies such as Knowledgeware, Texas Instrument's IEF and Accenture's FOUNDATION toolset (METHOD/1, DESIGN/1, INSTALL/1, FCP)
INTRODUCTION:
Computer-Aided Software Engineering (CASE) technologies are tools that provide automated assistance for software development. 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. A survey of the CASE tool market showed that the annual worldwide market for CASE fools was $4.8 billion in 1990 and grew to $12.11 billion in 1995. Behind such a prosperous CASE market, however, another result gained from the real investigation about the use of CASE tools revealed that CASE tools seem to be sparsely used after being bought in many enterprises. 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.
RESULT:-
Thus the STUDY OF USE CASE TOOL was studied.
