Discussion for Data Modeling Learning Tool

A very interesting idea. I only browsed through the applet and its demo, but the idea of allowing students to enter functional dependencies and produce an entity-relation diagram out of it is a good one. The instructions are minimal and it assumes that the user already understands the concepts of functional dependencies and normalization to some degree already. This is worth a more in-depth look.
The applet runs fine but the internal windows are rather small and surrounded by a great deal of blank grey space. Some of the applet boxes have 'close' buttons while others do not. The interface could use some improvement in consistency and rejigging in appearance.
