I think there are some issues with most databases. First of all, there 
certainly are reserved keywords like SELECT, FROM, WHERE and so on, but 
nobody can forbid you to name your java fields likes this. So we would need 
some conversion (like appending something) here. Another problem is, that 
most databases have a maximum length for names, ignoring everything after the 
n-th character. This could result in different names being cut of ending up 
the same. So we should cut up, say, at n-2 and add an increasing number. Same 
problem for classes in different packages. There was an interesting thread on 
www.jdocentral.com a few weeks ago.

However, this certainly isn't that important. We could use the 
simple-conversion as long as we introduce some hooks to add the advanced 
functionality later.

ciao Sebastian
