SQL is nothing more than a grammar for compiling data access functions,
nothing less.

ABSOLUTELY NOT. SQL is not a model. There are models build upon SQL, but
there is no requirement that data in the database is relational.

This is absolutely wrong. A simple key/value table in SQL is perfectly
fine. Why would anyone assert otherwise? The fact that you *can* use it as
a relation is beside the point.

Exactly, you are the one who brought up "relational" and the OP only
mentioned SQL.

In this discussion, "relational" is an empty strawman and does nothing for
the discussion.
