Which Database (MySQL, Oracle, mSQL, Protgress etc.)

 I need to use a database for a web site that implements stock trading. We need to
be able to support 500,000+ users where each user will have his/her account along with his/her portfolio, transaction history, etc. the database needs to be access over the web.

there will also be transaction involve where at the end of the day users order (buy, sell etc.) will need to e executed.

I need a database that is robust, scalable and that can support a lot of records and tables.

I heard about MySQL is it any good? how well does it compare to Oracle or Sybase. Received on Thu Feb 19 1998 - 00:00:00 CET
