I wonder how a tool can create an ERD from a database, since the steps from ERD to Datamodel are not 1 on 1..... Some decisions like resolving arcs, m-n relationships, (de)normalization etc will "disappear" in the process.

Happy Fish combines ERD design with live database access to query or maintain an already developed database.

I think they confuse an ERD with a Data Model Diagram....

Still looks useful though......
