server

Hello,
I would like to make a server for a chat and I wonder whether a server must, for example, connect to MySQL whenever a client enter to a room to check if he is moderator or banned from this room.
Is it necessary that I use MySQL to update the number of connected clients whenever a client go to another room(to display the number of connected clients on a web page)?
