        As argued in http://dbdebunk.com/ and elsewhere, SQL is not relational.
  Also, so-called object/relational DBMSs are even further away from the
relational model than SQL ones, and aren't even DBMSs proper, but
DBMS-construction kits.

        This is not a trivial matter, as SQL not being relational keeps it from
fulfilling the possibilities of the model, which would fulfill all the
requirements for which OODBMSs are built.
