WebSphere/ Message Broker

■Overview

■Capabilities

Messages Brokers can ensure that applications receive data in the proper format w/o knowing aynthing except their own conventions and requirements.
The broker can do the transformation outside of the applications, allowing deverse applications to work in concert. This is valuable for legacy applications which do not need to be changed.
