Automation shortening production systems

There are many compelling reasons to use CASE tools. CASE tools can greatly shorten development times without sacrificing system quality. The tools usually enforce consistency across different phases by providing automated consistency checking between DFDs, ERDs, and the data dictionary to ensure that the attributes and data structures have been named and defined consistently across all of them. This, in turn, can increase the productivity of the SDLC team because a data store defined in a DFD can be automatically inserted as an entry in the data dictionary. This, in turn, can increase the consistency of the development effort across projects.
