Well, on the server side there is a desktop application that is used to insert some information into the database (news, images, ect ..), and I have clients who collect this information from the database and store them in their local XML.
Thus, each client downloads news from the database and displays them.
The problem is how can I notify clients that there is an update.
My decision
I thought, using a database registered as UpdateID, and each time the data in the database is updated, the UpdateID should be increased by +1, then each client should have the UpdateID attribute in its XML and check if its UpdateID matches Server UpdateID, if not than this is a new update. For each successful update, clients must place the UpdateID server in their XML UpdateID.
So is there a better way to achieve this?
PS: The level of re-presentation of the data that it uses is a WCF service
