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.

Technical Remarks:

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.

Used in course
