Would require more than a few sentences. But mostly, it's about the very 
nature of the Zodb : it's a giant graph of Python objects.

So :
1/ your "data" are _very_ tightly dependant on the language and 
applicative code
2/ you have to hand-write each and every graph traversal
3/ accessing a given object usually loads quite a few others in memory


I once thought the Zodb was cool.
