It all comes back to how you arrange your data. It's probably the case 
that there's a more natural way to arrange your data in the ZODB than 
just duplicating the pattern you're using in a relational database.

Quite often, you need to think about your data a bit differently to get 
the benefits from an OO database.

You'll probably want to look at using BTrees and such.
