Like Derek said, it depends on your application. Here's an extreme example where everything is going on at the client: Suppose that your application was written using MS Access, and you've got the database on a server somewhere, and users can open up their local copy of Access, and use the 'client' .mdb file that you've written. Whenever they do a query on the database, they're basically reading the data from that server machine, and you're really only using the server as a disk server, as opposed to a true client-server relationship. The server doesn't have to do much, but there's a lot of stuff flying around the network. Now suppose that instead, you've got a server somewhere that's running an Oracle db, and users have client applications that display forms and query the database. The server will do all the heavy processing (accessing the database to run queries), and will only transmit the results to the clients. The server has to do a lot of work, but you're keeping your network traffic as low as possible by only sending what's required. Matt Lewis
