Step 1 CASE: It stands for Computer Aided Software Engineering or Computer-Aided System Engineering. It is a process of software development with the help of some specialized tools. In this process, computer-assisted methods are used for managing and developing software. This process is used for large and complex projects. It helps to maintain an organized and structured way for software development. CASE is used by all the coders, developers, testers, and so on, so that they can share and have a look at a common stage to know the stage of completion. Step 2 CASE Tools: CASE tool is a software development tool which is used by the system analyst to develop information systems. It is a computer assisted method in which software development and maintenance phases are controlled by software tools. The main objective is to automate or support activities through the system development process and is used to increase productivity and to improve the overall quality of the system. CASE helps to manage complexities in information systems and also helps to ensure high quality systems which are constructed on time and within budget. Step 3 CASE repository and its uses: A CASE repository is an integrated and standard database which is a common method for providing product and tool integration. A CASE system uses repository to identify objects and rules for reuse. A CASE repository is actually a representation of all relevant information about the developing system in a complete and consistent form. It is a centralized database which contains all diagrams, forms, process flows and definition of other organizational and system components. The general types of CASE tools and its uses are described as follows: Diagramming tools enables the system process, data and control structures to represent graphically. Computer display and report generators helps prototype to know how the system look and feel to users. Analysis tools checks incomplete, inconsistent or incorrect specifications in diagrams forms or reports. The central repository that enables integrated storage of specifications, reports, diagrams and project management information. Documentation generators helps to produce both technical and user documentation in standard formats. Code generators enables the automatic generation of program and database definition code directly from design documents, diagrams, forms and reports.
