> MySQL alone cannot represent a complex data-structure. > not true at all, it's just not object oriented but don't you know that there is still no good (consistent and "complete") theoretical model for OO-DBMS. Relational Model _has_ good underlying theory and I think this is the main reason of worlwide success of RDBMS.

I'm afraid there could be no automation for most general kind of semantical modifications. 2.The more flexibility and dynamic behaviour (of the system) you want the more overhead you'll get (in general). -- Best regards, Yegor __________________________________________________________ Yegor Bryukhov, PhD student at GC CUNY office: 4330 office phone: +1(212)817-8653 home phone: +1(718)842-4250 e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
