And yes, I have met with Codd, Date and Goodman on this very >issue. This argument reminds me of those interpreting an artist's paintings... "this was painted during so-n-so's blue period... he was distraught and depressed... you can tell this from his choice of colors." Well, maybe the artist just ran out of red paint... or perhaps, the artist took advantage of a fire sale at the corner DIY art supply store. In the Pick/U2/MV model, we're mainly dealing with business applications. As such, the more relevant questions shouldn't revolve around relational, but instead does xxxxx model allow an application to perform well, adjust easily to a company's changing needs, provide a robust, performant, and easy to maintain environment, etc. Most importantly, does i xxxx model allow a company to focus on, and increase the bottom line of their business. It really shouldn't be about one technology vs another. -Laura _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
