WBIMB (WebSphere Business Integration Message Broker)

In short (though the acronym it already that long), WBIMB transforms and enriches in-flight information for a further level of intermediation between applications that use different message structures and formats.

Go figure!

"If you are considering Web Services architectures and solutions, the broker can assist with integration of non-Web-Services applications, the routing and transformation of SOAP messages, and the logging of Web Services transactions. An improvement on point-to-point Web Services implementations that can lead to complex application interdependencies, the brokers help to improve control, simplify application development, lower maintenance costs, and increase flexibility. When combined with WebSphere MQ you gain essential reliability to web service."

Aha.
