Any fun way to use DTP with jdbc to hook into some tables from db and make a nice ER(entity relationship) diagram for database (sql etc.)?

DTP has an EMF model that represents the database catalog and which forms the basis of the tree in the Data Source Explorer view. It is populated (by default) using JDBC. See the model and classes in the org.eclipse.datatools.modelbase.sql plugin. The model is populated using the classes in the connectivity component, particularly org.eclipse.datatools.connectivity.sqm.core.

There are diagrams showing the catalog meta-model available at http://www.eclipse.org/datatools/project_modelbase/modelbase_doc/SQL_SQLQuery_ModelWebPub/root.html

By the way, the IBM product InfoSphere Data Architect produces ER diagrams from the database information such as you suggest. It is based on the DTP code.
