Short Note on CASE Tools

CASE Tools :-

CASE (Computer Aided Software Engineering ) tools are the programs that provide support in one or mores pages of system development process.

                                        CASE tools are available for most of the analysis and designing work and they allow the system analysis and designers to concentrate on the creative aspects of the design.

Objective :-

The objective of CASE tools is to help system analysts and designers is developing good quality systems within the specified time and budget constraints.

Case Tools are the Following Types :-

1 . Analysis tool , 2 . Diagrammatic tools, 3 . Display and Report generators, 4 .Code generators, 

5 . Documentation generator, 6 . Testing and Debugging tools.

Case tool can be used in the need identification, System planning, Analysis Design and implementation phases of SDLC.

Proper use of tools would improved the effectiveness as well as the efficiency of the system development.

Advantage :-

1 . CASE tool improved speed and reduce the time needed to complete a particular software                     development task.

2 . Development of DFD , Gantt chart, PERT chart can be very tedious if done manually. CASE tools       take away most of such drudges.

3 . When procedures are coded by a CASE tools they give a consistent look.

4 . In addition to the enforcement of consistence tools, CASE tools can also ensure completeness.

5 . Use of CASE tools increases the likelihood of meeting user requirements.

6 . One major advantage of CASE tools is that it facilitates prototype.

Disadvantage :-

1 . There is no standardization yet among the different CASE tools available in the market.

2 . CASE tools generally used diagram to represent the modeling and reporting of analysis and                 development work.

3 . Case tool have a limited scope.

4 . A bad analysts or designer  can never become a good analysts or designer by just using a                    sophisticated  CASE  tool .
