Response to: Is an ORDBMS not just another persistence store for JDO?

JDO has no means of supporting methods calls for UDTs. So the use of JDO would mean the objectbase would be nothing more that a UDT database.

    But JDO associates a Java class name with each instance stored in the database, so effectively it is defining method calls on UDTs. It would be possible to have a JDO implementation which serialized class files to the DB at the time they were enhanced and used a custom class loader to load the class as the data was retrieved.
