You Don’t Need a CASE Tool
Computer-aided software engineering (CASE) tools were invented to run on personal computers or workstations and to help analysts with record keeping and with some rule and consistency checking. This means that a computer, rather than paper, is used to store and access the data flow diagrams, data models, data dictionary, and the other components of the requirements specification.
CASE tools can be very useful, and, no doubt with the very large projects that lie in your future, CASE is going to be a necessity. However, while the Project in this book is quite large, you are never asked to build such uncontrollably large models that they cannot be handled using pencil and paper.
If you are new to systems analysis, we recommend that you not use a CASE tool until you feel comfortable with the modeling techniques. Some tools have procedures for building models that will confuse you and that will get in the way of your learning about systems analysis.
