There are usually 2 components needed to run a database driven web site: a server-side scripting language and the database itself. You have the server-side scripting language query the database to select, update, delete and modify records.
Server Side Scripting Languages:
ASP
ASP.NET
PHP
ColdFusion
Databases:
SQL Server
MySQL
Oracle
Access
Postgre
MSDE
There are obviously many that I have missed but that's a basic list.
