Classical ORM is limited by the fact that it's mapping unidirectionally object language -> relational language.
I think I maybe see where you're coming from here. Are you talking about the automatic generation of a new OO API definition from an existing database schema, and the reverse operation of automatically generating a new database schema from an existing OO API? In that case, my answer would be: I thought several ORM frameworks are capable of that? It's been a while since I worked with them though so I'd have to look it up, which I don't have the time for right now, plus I'm not sure if I'm understanding your question correctly...?
