CASE : Computer-Aided Software Engineering. CASE tools are defined programming rules for applying engineering principles, methods, techniques, and concepts. These tools assist in accomplishing a definable engineering task in the software design process by automating manual activities through structured prototyping. This technique reduces customized development time, supplying consistent code sets and supporting the entire software life cycle process.
