An application would like to transfer data to another application. It could do so using File Transfer or Shared Database, but those approaches have shortcomings. The transfer might work better using Messaging.

How can messaging be used to transfer data between applications?

Use a Document Message to reliably transfer a data structure between applications.

Whereas a Command Message tells the receiver to invoke certain behavior, a Document Message just passes data and lets the receiver decide what, if anything, to do with the data. The data is a single unit of data, a single object or data structure which may decompose into smaller units.
