In short:
Any O/R map tool has the DB model loaded in a set of diferent Java
Objects. That way, we have to worlds that need to be synchronized: The DB
world and the Object world. See:

http://db.apache.org/ojb/faq.html#How%20is%20OJB%20related%20to%20ODMG%20and%20JDO?

Some API does not support the Object transaction level. This is the case
of PersistenceBroker in OJB.
