we need CASE tool during system development because: As the special emphasis is placed on the redesign as well as testing, the servicing cost of a product over its expected lifetime is considerably reduced. The overall quality of the product is improved as an organized approach is undertaken during the process of development. Chances to meet real-world requirements are more likely and easier with a computer-aided software engineering approach. CASE indirectly provides an organization with a competitive advantage by helping ensure the development of high-quality products. Types of CASE Tools: Diagramming Tools: It helps in diagrammatic and graphical representations of the data and system processes. It represents system elements, control flow and data flow among different software components and system structures in a pictorial form. For example, Flow Chart Maker tool for making state-of-the-art flowcharts. Computer Display and Report Generators: These help in understanding the data requirements and the relationships involved. Analysis Tools: It focuses on inconsistent, incorrect specifications involved in the diagram and data flow. It helps in collecting requirements, automatically check for any irregularity, imprecision in the diagrams, data redundancies, or erroneous omissions. For example: (i) Accept 360, Accompa, CaseComplete for requirement analysis. (ii) Visible Analyst for total analysis. Central Repository: It provides a single point of storage for data diagrams, reports, and documents related to project management. Documentation Generators: It helps in generating user and technical documentation as per standards. It creates documents for technical users and end users. For example, Doxygen, DrExplain, Adobe RoboHelp for documentation. Code Generators: It aids in the auto-generation of code, including definitions, with the help of designs, documents, and diagrams.
