Write a program that populates each with the same large set of randomly generated data, measure memory usage and performance for some typical queries. I'd expect that the results will prove that a single table works best. However if it doesn't, at least you have a justification for making a more complex, more expensive (to develop) and harder to maintain solution. -- RGB --- * Synchronet * The Whitehouse BBS --- whitehouse.hulds.com --- check it out free usenet! --- Synchronet 3.15a-Win32 NewsLink 1.92 Time Warp of the Future BBS - telnet://time.synchro.net:24
