i am quite new to distributed systems and at the moment im building a centralized service that will hold data which mulitiple clients can access.This data may change and clients subscribed to the service should be notified of this update. A notification should be made automatically. In this case the client is not invoking a webservice notification function so im not sure how to do this? what are the different ways of solving my problem? any suggestions as i can have different clients using different methods solving my problem. this is an experimental project.
