If you *really* want to do this with the right architecture, I would
recommend you steep yourself in Enterprise Objects Framework (from
Apple, formerly NeXT).  This is *way* ahead of anyone else's
implementation and is based on a lot of graph theory and faulting. 

For more information, you should read:

on providing a UML model of them, but it's pretty extensive.
