In some magazine (PC Week?) recently there was an interview with some
consultant from Codd & Date.  He was asked which products on the
market were really relational databases.  He mentioned Oracle and a
few others.  He then said Informix had "honorary mention" in that
group because it was a relational interface built on top of a non-
relational (C-ISAM) engine.  (BTW, neither Unify nor Ingres was
mentioned at all.)

I guess I don't understand what a truly "relational engine" is in that
sense (i.e.  why Informix doesn't qualify).  And what about Ingres
and Unify?

Any enlightenment appreciated.
