Sure. Google for SQL Server Notifications (pre SQL Server 2008 R2) or SQL Server StreamInsight.

Using Ajax to do this wouldn't be efficient because Ajax cannot sit there and listen for notifications. It has to poll the server for any changes. This increases the load on the server as the number of clients increases.

You could use SignalR to do this though. Google for that too.

5ed (very basic and short though, but a reasonable inquirer would get a right idea on what to look for).
