I'm simply writing object oriented applications that need persistence, and as you seem to have noticed (since you claim that OO model is founded on nothing), RDBMS and ER model in general is obviously unfit for the purpose.
Its a well know fact, here, have a look:

Access to objects in object-oriented programs is allegedly best performed via interfaces that together provide the only access to the internals of an object. Similarly, essential OOP concepts for classes of objects, inheritance and polymorphism, are not supported by database systems.
In particular, relational database transactions, as the smallest unit of work performed by databases, are much larger than any operations performed by objects in object-oriented design. ...

Oh but it does, object cannot have reference to a deleted object (referential integrity), simply setting a member to null prunes entire subtree (cascade delete), setting member value to anything else reflect this value to all referrer object (cascade update), etc, etc.

I suggest you rephrase your question to emphasize expected answer more clearly.
Or why not just tell me, you _know_, right?

Well thank you for your correction; I'm glad no informed and reasonably intelligent person have seen my writings yet.

Errr... how about you take a course or two in OOP? You might dig that in just a few hours...
