	So does this mean an object oriented dbms can not, by performance
	necessity, be built above a rdbms?  (If performance is the key, than
	an oodbms built in such a manner would require some heavy duty
	optimization - the joins would be incredible).  It also 
	makes sense that adding another layer would make a slower
	system - comparable to an extended rdbm.

	Now, if the oodbms is not built above the "proven" relational algebra
	what should it be built above? Prolog? Now what are we talking about?
	Object-oriented DBs or deductive DBs?
