I am developing a Client-Server application using C# .NET Winforms with SQL Server 2008. The client pc’s connect to the database server via the LAN.

The task I want to achieve is when an insert (or update or delete) is performed on one client-PC, all other clients must get that update in real-time.

I am currently using timers, so that each client queries the database every 15 seconds then refreshes the gridviews, combo boxes and list boxes. But this makes the application slow and bulky to use.

What is the correct method to use in such scenario. What are such operations called (correct terminology)? Should I use windows services? or same application with background threads ?

    First of all, its Windows, so it cannot ever be realtime.

    The solutions that – Igby Largeman suggests is well possible. It does have the disadvantage that it can cause very heavvy network traffic, because every time something changes in the database, it is broadcasted to all the clients.

    You also have to consider the possibility that something clogs ub the communication between the server and one or more clients, so realtime is out of the question.
