To all,

I am wondering if there is a pattern or a set of them that can help with my problem. We have a 2 tier application and the UI "queries" the server and the results come back asynchronously. This messaging is in need of a good overhaul/refactoring.

Are any patterns or any standard approaches that can help in this area. My thoughts so far are:

Queries or request are generated, the results of queries "trickle in" not atomic, I need a middle layer to handle this query submition along with putting the returned packages together and when finalized notify the UI, that hey we got results for a query.

Does this sound reasonable? If so, any patterns to implement this idea.

Regards,

Reza
