I'm a J2EE developer & we are using hibernate mapping with a PostgreSQL database.

We have to keep track of any changes occurs in the database, in others words all previous & current values of any field should be saved. Each field can be any type (bytea, int, char...)

With a simple table it is easy but we a graph of objects things are more difficult.

So we have, speaking in a UML point of view, a graph of objects to store in the database with every changes & the user.

Any idea or pattern how to do that?
