Applications communicate with each other by exchanging messages on queues. The main use of IBM MQ is to send or exchange messages. One application puts a message on a queue on one computer, and another application gets the same message from another queue on a different computer.
IBM MQ channels are used to connect one queue manager to another over a network. You can create MQ channels yourself, or a queue manager can join a cluster of queue managers where MQ channels are automatically created when they are needed.
With the help of a Message Queue, better communication and coordination can be provided to these distributed applications. In short, MQ allows applications to communicate with one another by sending messages. Companies need to analyze their business data stored in multiple data sources.
