Free/OSS Data model diagram generator from DDL?

SQL Power architect has a GPL version (though it looks like they are releasing an 'Enterprise' edition soon) There is also FabForce's DBDesigner, though it is more geared to MySQL (but has some Oracle capability).

You could also look at sql-developer and data-modeler from Oracle. Both are free oracle.com/technetwork/developer-tools/d....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
