Free/OSS Data model diagram generator from DDL

问题:

I am looking for some free/oss to reverse engineer from DDL a data model diagram.

My database is Oracle if that matters.

Do any exist?

回答2:

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
