        This has been long refuted by The Third Manifesto.

        Just a small sampling: the chapter about types and classes is fuzzy, even if it kind of tries to avoid The First Great Blunder. But above all, the Object Identity chapter violates the Information Rule, and thus brings back upon us all of the network databases evils and curses by incurring in the Second Great Blunder.

        That's The Second Great Blunder.

        By all means, then do so where no one will question you, namely news:comp.databases.object.

        Last time I tried to wade thru your website it was brochureware full of buzz, hype, marketspeak. You've been asked for examples already.

        To give you the benefit of rule, I've waded thru your tutorial. Again, navigation instead of declaration, only simple stuff given, no consideration to logical and user schemas. Please try better.

        Never had the pleasure of seeing such a post. Just to give you the benefit of doubt, I did a quick search thru http://groups.google.com./groups?hl=pt&lr=&q=carl+rosenberger&btnG=Pesquisa+Google&meta=group%3Dcomp.databases.theory and found nothing as you claim, just more physical and logical levels confusion, ignorance of the relational model and more First and Second Great Blunders instances.

        Please try to convert me by giving nicer pointers than those I've been able to find.

        Then please stop trolling, start real discussions.

        Sometimes an insult is a way of trying to show someone he's been irritating by refusing to learn, instead ignoring all information and arguments to be able to keep proclaiming his own correctness.
