CASE tools are the tools used while developping a software project.

software engg (somervellie)

There are a number of CASE tools available for your use in system and database design and implementation such as Rational, ERWin, Visual Paradigm etc.

1. Upper Case Tools support strategic, planning and construction of conceptual level product and ignore the design aspect. They support traditional diagrammatic languages such as ER Diagrams, DFD, UML, Structure charts etc.
2. Lower Case Tools concentrate on the back end activities of the software life cycle and hence support activities like physical design, debugging, construction, testing, integration of software components, maintenance, reengineering and reverse engineering activities.
3. Integrated Case Tools support all stages of the lifecycle and provide the functionality of both upper and lower case tools
