Not a lot. It does not have anything special.

I designed it taking the Principle of Orthogonal Design into account.

But Hugh Darwen told me recently that Date and himself are reconsidering the POOD.

I also have doubts about the representation of expresions, like views, constraints, operators code, etc.

I am representing expressions with directed acyclic graphs represented by relations, but I am not sure about it is a good approach.
