In modern ZODB versions (I think ZODB 3.6 and above),
there is an iterator which allows you to iterate over
all objects in the ZODB.

It main use case is to perform migrations between major updates.
But, if you know how to "list" your objects intelligently (this is much more
difficult than with Oracle where all objects have a strict schema),
you definitely can do this as well (but I doubt, you will be happy).

The ZODB level is *very* *very* low!
You do *NOT* want to work on this level when you have an alternative...
