Documentation: In a traditional software development process, the quality of documentation at various stages depends on the individual.

It also ensures the completeness of the documentation. Project Management: It improves project management activity and to some extent automates various activities involved in project management. Reduce the maintenance cost: Use of CASE tools makes the software easy to maintain and hence reduce the maintenance costs. Increase Productivity: Automation of various activities of system development and management processes increases productivity of the development team.

That's why software developers always looking for such CASE tools that help them in many different ways during the different development stages of software, so that they can understand the software and prepare a good end product that efficiently fulfill the user requirements. CASE tools provide the integrated homogenous environment for the development of complex projects. These tools provide computerized setting to software developers to analyze a problem and then design its system model.

The CASE tools also provide the environment for monitoring and controlling projects such that team leaders are able to manage the complex projects. Reduce development time of the project as they support standardization and avoid repetition and reuse.

Develop better quality complex projects as they provide greater consistency and coordination. 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:. The job of a systems developer may contain requirements analysis, process design, data design, and programming among other activities.

But, not all systems developers do the same activities. One may spend most of his or her time on analysis; another, on design. The various activities that the system developers involve include Systems Analysis including feasibility studies and requirements definition , Systems Design including user interface, data, and process design , Programming or generating code ,.

Testing, Supervisory or other management tasks and Maintenance. CASE tools play an important role in helping the system developers to perform the task efficiently. Decision table checking. Screen design for data inputting. Form design for output.

Improve the productivity of the systems development process. Improve the quality of the systems development process.
