UML + some UI

Guess that means me. But then, I'm an academic, so that probably doesn't 
really count... ;-)

None - I've always done smaller projects (research prototypes...) that 
didn't need that level of planning.

Check out the model-view-controller pattern. Essentially, it's about 
separation of data vs. display vs. modification code. Each of these 
fields get their own set of classes.

Not quite sure where inheritance comes into the play. You'll want to 
create a database class (or set of classes) that publish the interface 
to modify/query etc. the data. That interface is *used* by your UI 
classes, not inherited.

You might want to take care to seperate out the interface to the db from 
its actual implementation, but that's not really the topic of this 
exercise as I understand it...
