That does not imply.

If you concede that in your system it would be OK to use SQL together with an OOPL X, then your argument of hiding SQL behind the scenes does not work. Because alleged technical merits of SQL should in some way show themselves in the design. That is the DB-guys point. (They go further and propose to scrap X.)

My position is opposite. It is that SQL does not have such merits, it is there only as an interface to a legacy component. If that component had an OOPL X interface I would take it instead. It might appear radical, but in fact this is what all those zillions of language X-to-DBMS-Y bindings are about.
