Is there any good methods to solve this problem? thank u

If your are using SQL Server check out SqlDependency. Here are links to MSDN with examples of how SqlDependency can be used:

I'm thinking loud here.. if you can't use SqlDependency, the next thing you can try is FileWatcher, but you won't know what changed..
