Message Construction

Message construction involves the architectural patterns of various constructs, functions, and activities involved in creating and transforming a message between applications.

This chapter introduces message construction patterns and how they can be simulated using the WSO2 Micro Integrator.

Command Message		How messaging can be used to invoke a procedure in another application.
Document Message		How messaging can be used to transfer data between applications.
Event Message		How messaging can be used to transmit events from one application to another.
Request-Reply		How an application that sends a message gets a response from the receiver.
Return Address		How a replier knows where to send the reply.
Correlation Identifier		How a requester that has received a reply knows which request the reply is for.
Message Sequence		How messaging can transmit an arbitrarily large amount of data.
Message Expiration		How a sender indicates when a message should be considered stale and therefore should not be processed.
Format Indicator		How a message’s data format can be designed to allow for possible future changes.
