Lockheed Martin (texas) did it for IETMs using SGML. It was a favored design for IETMs. It wasn't efficient for real time use, but for dynamic assembly of a deliverable, it worked great. IOW: 1. Author parts in a parts system, typically relational. 2. Bind that into an interactive deliverable. And yeah, isn't that what we do with HTML and ASP, PERL, etc.? All done before the web was a gleam. A dynamically generated hypertext is just another report, or a collection of reports with scriptable intelligence. Do I need schemas for that? Not all the time. That is why systems like IADS made validation optional. In fact, support for DTDs was an add-on that I insisted on just because it made my job easier. We worked the CASS system the same way even earlier. Old ground. You're right about the object-oriented standards issue, IMO. I still think data objects scale better than distributing semantics, though. len From: Michael Champion [mailto:mc@x...] My favorite example would be an industrial-strength technical manual. Codd proved that you CAN normalize all that ordered, hierarchically structured, textual and data-oriented information and pull it back together with the relational calculus, but I've never heard of anyone actually pulling that feat off with real data and real DBMS software. [Sure, just a simple 100-way join, no problem :-) ]
