Do you also agree that some of the data models that are not considered by relational theorists to be relational are, in this way, actually MORE relational in that they do require logical constructs (ordered tuples) that correspond to mathematical relations? This is one of several issues I'm trying to square away or at least get a vocabulary that is not so contradictory. Thanks --dawn
