Huh? I know of the lambda calculus as a foundation of functional languages and the relation model as foundation of RDBs. But I wonder what the formal foundations of the OO family of languages is (references, please).
As far as I understand those matters I would say the relational model is more abstract than the OO model (only the most common language use for the relational model, SQL, is... improvable).
