Right now there is a wonderful thread in comp.database.object where this
questions has been discussed over and over again. If possible, take a look!
Database objects (proxies) should be considered as simple Java objects. How do
you identify the objects of your application? You are traversing the object
graph, I guess. This is the same with persistent (database) objects. The same
code works with normal and persistent object. That's the goal, that's the
trick! Now, before you ask if this is inefficient compared to an query language,
please read the mentioned thread in the news.
