MQSeries, by IBM, is a messaging system that allows heterogeneous computer systems and software to exchange data. The information is exchanged through messaging queues managed by the Queue Manager responsible for receiving messages and making them available on the network for other systems to use. MQSeries also comprises a library of functions for developers to use in their own applications. This library is a common programming interface known as the Message Queue Interface (MQI).
With over 35 supported platforms, MQSeries is the ultimate solution for computer system and information integration.
