Characteristics of CASE Tools

Below are some features of CASE tools of software engineering which emphasize how they function and the ability to use them effectively.

CASE Environment

A CASE (Computer-Aided Software Engineering) environment comprises a set of tools and techniques along with a central repository (the shared database) in which software engineers can apply various forms of automation to manage the different stages of software development. The central repository supports CASE tools inputting and storing any project-related documentation, along with integrating other CASE tools acknowledged within a repository or by their own structure.

These tools assist in coding, project management, prototyping, configuration management, technical writing, documentation generation, structured design, analysis, and reporting. CASE environments strive to increase product quality; maintain consistency of product identification throughout development; improve communications with members of the team; and decrease development time or cost.

Components of CASE Tools

Depending on the stages of the Software Development Life Cycle, the components of computer-aided software engineering CASE tools can be categorised into three primary groups. Each type plays an essential role in facilitating specific stages of software development and providing efficiency and consistency.

Central Repository

The central repository is one of the key components of CASE tools. It serves as a shared database that can contain all the information about the project, such as the system models, documents, design, etc. The central repository is designed to facilitate consistency, accessibility, and cooperation among developers, testers, and project managers.

Categories of CASE tools

CASE tools are organized into three basic categories as determined by their purpose during each phase of Software Development Life Cycle (SDLC), below are categories of CASE Tools:

1. Upper CASE tools

Upper CASE tools support the earlier part of the software development, planning, and requirement and system design phases. These stages have documentation, diagrams and modeling, which are an important part of the process that go into developing a good plan or blueprint for your software. Examples of upper CASE tools include ER diagrams, data flow diagrams (DFD), and UML modeling tools.

2. Lower CASE tools

Lower CASE tools support the later phases of the software development process, such as the coding, testing, debugging, and maintaining the software project. In these phases, generating code, detecting errors and finally deploying the software can be automated by the CASE tools. Examples of lower CASE tools include compilers, debuggers, and test management tools.

3. Integrated CASE tools

An integrated CASE tool provides full end-to-end support for all stages of the systems development life cycle. Integrated CASE combines Upper CASE and Lower CASE.
