Disk space and memory truly were expensive...in the 90s. Joomla was born in 2000 though.
Here's a (hopefully) interesting little story. I once got into a huge, heated debate with a consultant about data modeling. His argument was that random incrementing integers were bad design and negated the benefits of primary keys. His biggest beef was that your table already had a primary key - even if it was a composite key - and that slapping an integer on there would only cause you pain in the long run. This pain sounds a LOT like the data migration issues everyone has with all these random, incrementing integers as primary keys :-) For the record, the conversation was at ClassMates.Com waaaaaay back around 1997. I thought the guy was a total loon. However the more I think about it, the more I realize he was just ahead of his time. Back then we still needed those integers for all the bazillion JOIN operations across tables with more than fifty million rows each... As everyone starts to denormalize their data models however, this will become a bigger and bigger headache, as all your logic is tied to those numbers when all that is really important to YOU is the post's title, the user's username, component's name, etc. -- Mitch _______________________________________________ New York PHP Users Group Community Talk Mailing List http://lists.nyphp.org/mailman/listinfo/talk http://www.nyphp.org/Show-Participation
