Since Its programming Interface Is easy to understand, It Is mostly available on operating systems.

For example, in a communication, a client invokes these procedures the same way a server exports several procedures. By facilitating message exchange, the message-oriented middleware generally supports he communication between the distributed systems. Using the global data base, components can be communicated with by publishing and subscribing to data. Communications are not synchronized.
