OK, but I'm not talking about any currently existing DBMS here.

Yes, but are imperative languages a good match for DMBSes? I'd suggest that it is *because* they have variables that they are not a good match. People look at those local variables and start wanting them in the database. They create an artificial split between data in the database and data not in the database. We want all data to be only in the database.

All in all, something more functional would work better.
