Notification Server

28. July 1998

In enterprise information systems based on a two-tier distribution architecture, there are several clients working with shared resources. When designing the system you have to ensure that each client has a consistent view on the current state of the shared resource. If the resource in question is passive, i.e. the resource is not able to notify interested clients about changes of its (internal) state, attaching a Notification Server to that passive resource helps achieve a consistent view for each client.
