Structuredanalysisanddesign withCASEtools Several diagramming techniques are used for structured analysis and structured design. Thefollowingsupports mightbeavailablefrom CASE tools. ACASEtoolshouldsupportoneormoreofthestructuredanalysisanddesigntechniques. Itshouldsupporteffortlesslydrawinganalysisanddesigndiagrams. It should support drawing for fairly complex diagrams, preferably through a hierarchy oflevels. The CASE tool should provide easy navigation through the different levels and throughthedesignand analysis. The tool must support completeness and consistency checking across the design andanalysis and through all levels of analysis hierarchy. Whenever it is possible, the systemshould disallow any inconsistent operation, but it may be very difficult to implement sucha feature. Whenever there arises heavy computational load while consistency checking, itshouldbepossible to temporarilydisable consistencychecking. Codegeneration andCASEtools As far as code generation is concerned, the general expectation of a CASE tool is quite low.
