I'm looking for a template shape which allows the table name to be expressed in a header, then the table columns below it. For each column, the shape should support capture of the column name, data type, and whether the column is part of a key.
Here's a good example: http://pic.dhe.ibm.com/infocenter/brdotnet/v7r0m2/index.jsp?topic=%2Fcom.ibm.websphere.ilog.brdotnet.doc%2FContent%2FBusiness_Rules%2FDocumentation%2F_pubskel%2FRules_for_DotNET%2Fps_RFDN_Global453.html
Relationships between columns/tables could be created using the existing connectors I think.
Hopefully this example helps explain what we're after
