Message Oriented Communication

Uses messages to communicate with different systems to perform some kind of function.

• A collection of data fields sent together between sender and receiver
• Contain information on what action is requested from one end point
• Header + Payload
   

• Asynchronous or Synchronous Communication
• Persistent or Transient Communication
   

Pros:

• Loose Coupling
• Easier Message routing and Transformation
• More flexible payload (binary attachments)
• Good for homogeneous and heterogeneous systems

Cons:

• Added complexity of message handling code in client and server
• Risk of losing type information
• Transactional context in which the message was sent does not propagate to
  the message server
