As you you already read at the title page, UML .FRI is a CASE (Computer Aided Software Engineering) tool. The goals of this tool are a bit different then other CASE tools have. UML .FRI exists primarily to help computer science teachers in teaching different modeling languages. I don’t say, software engineers are discouraged from using it if they want. But they are not the target group.

Design goals (or features if you want)

There are some things I still keep in my mind when designing new features. You can find some of them here.
