We have a problem, Houston.

Data is data. Programs are something else. If you want to represent programs in a database, this has nothing to do with OO. Now if you want to overcome the so-called OO-RM "impedance mismatch", please read The Third Manifesto. You will see that type inheritance thru S by C is needed indeed, and a relvar is also a type. So that's it.

Now, if you think something else is required, please enlighten us.
