There is one server with multiple clients. The clients are viewing subsets of the servers entire data. If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data.
Example:
Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view.
In the client side code I would like the users list to be updated by the framework itself, raising changed events such that it will be redrawn – similar to ‘cells‘ or dataflow.
I am looking specifically for a .NET or java implementation.
The question is very broad so here is my very broad answer: yes, some databases support database-enabled publish-subscribe messaging than can be used to implement “server push”.
