What is publish/subscribe?
WebSphere MQ Publish/Subscribe allows you to decouple the provider of information from the consumers of that information.
Before a standard WebSphere MQ application can send some information to another application, it needs to know something about that application. For example, it needs to know the name of the queue to which to send the information, and might also specify a queue manager name.
WebSphere MQ Publish/Subscribe removes the need for your application to know anything about the target application. All it has to do is send information it wants to share to a standard destination managed by WebSphere MQ Publish/Subscribe, and let WebSphere MQ Publish/Subscribe deal with the distribution. Similarly, the target application does not have to know anything about the source of the information it receives.
