I had the need today to create an ERD for a set of customer tables using MyEclipse for Spring 10.1. For whatever reason, the tables were not defined with foreign key relationships. I tried to find a way to manually add the relationships, but the diagram still seems to be read-only, unless you modify the database itself. So the diagram is pretty much useless.
Please add the capability to add relationships to an ERD, or add a package that does so. Thanks.
