Re: Data Modelling Tools

I have to say that ERwin is pretty much the bomb. It indirectly
supports postgresql through ODBC, which I've used with much success.
It will also port your schema to another RDBMS system if you wish. It
can build a model from either a running database or DDL or by
construction, and will also output to all of the above. Very
excellent tool, but I think it's about $4k/license. Is it worth it?
hell yeah.
