CASE Tools
As discussed earlier, many systems development projects use CASE tools to complete
analysis tasks. Most computer-aided software engineering tools have generalized graphics
programs that can generate a variety of diagrams and figures. Entity-relationship diagrams,
data-flow diagrams, application flowcharts, and other diagrams can be developed using
CASE graphics programs to help describe the existing system. During the analysis phase, a
CASE repository
—a database of system descriptions, parameters, and objectives—will be
developed.
