        As I see it, rules must be enforced by the DBMS, the OS would never be
enough.  Unfortunately, there are rules that only would reasonably be
implemented in a RDBMS, of which the only available implementation is
proprietary, namely Alphora Dataphor.  One is left with a choice of
either implementing a true RDBMS, or instead use the least bad
approximation, which currently seems to be SQL.

        As for OO, it can't provide in itself a data model, integrity
constrainst and interactive manipulation, not even to the already low
SQL standards.  OO sure is nice to programmers, but not to end users and
DBAs.  And anyway one can do OO on a relational database nicely enough,
even if on SQL it is more of a chore.
