MOM (message oriented middleware) is a common name for two philosophies:

1) Point to Point (PtP)
   Somebody (point A) sends a message to someone else (point B).
   Usually the MOM server has a queue for messages when
   the receiver is currently offline.

2) Publish/Subscribe (Pub/Sub)
   A data source publishes its knowledge with messages to the
   MOM server (e.g. a wind speed anemometer publishes the
   current wind speed every 2 seconds).
   Data sinks subscribe to such informations and receive them
   instantly as a message/event.

Thats all about it - it is simple - it is powerful.

Follow some links on our 'Internet Resources' hompage
to get more vaiants of the above principles.

best regards - and don't give up,

Marcel
