Open source data modeler

Question

Is there any open source data modeler available? If yes, which is the best or closest to Rational Rose?

Answer 1

First, "data modeler" is vague. It helps if you define your terms.

Second, "close to Rational Rose" is subjective. Depends on which features you use and what you mean by "close".

Look at http://argouml.tigris.org/ for a good UML diagramming and modeling tool.
