Here is also a good example of how to connect Flash (client Browser) to PHP (web Sever) that talks to your database (any rdbms). The example uses Mysql but the same logic can be userd for any database. Also it's done with PHP but you can use any scripting language (php, cold fusion, jsp, asp, csharp, etc).....
