Akmal,

There is always a danger when a practitioner like me getting in the midst of a theoretical discussion like this that someone (like you :-) will ask for some documentation. Alas, I don't have any.

And I will concede Lee's point that my statement is unjustly broad.

However, for some non-empty set of applications (one might look at Telecom and other "traditional" markets for object databases), the performance of the object database is better than relational ones. Unfortunately, I can't offer much about my particular applications other to say that it is a data transformation/correlation process and empirically object databases outperform relational ones.
