Creating DataGroups
Universal Messaging DataGroups provide a very lightweight grouping structure that allows developers to manage user subscriptions remotely and transparently.
Each DataGroup is a resource that exists within the Universal Messaging realm server, or within a cluster of multiple realm servers. Creating a DataGroup - in this case using the Enterprise Manager - creates the physical object within the realm. Once created, references to the DataGroup can be obtained using the Universal Messaging Client and Admin APIs. DataGroups can also be monitored and managed using the Enterprise Manager.
When you connect to a Universal Messaging realm in the Enterprise Manager, all resources and services found within the realm namespace are displayed in a tree structure under the realm node itself. It is possible to view multiple Universal Messaging realm servers from a single enterprise manager instance.
