Implementing MOM queue elements

Question

How could database technology be the basis for implementing MOM queue elements?

Answer 1

In a message-based middleware system, the recipient's message not need replicate the sender's message accurately. The MOM system with built-in intelligence can convert messages en-route to match the requirements of the sender or of the recipient. In conjunction with routing and broadcast or multicast facilities, one application can send a message in its own native format, and two or more another applications might each receive a copy of the message in their own native format. Many modern MOM systems provide sophisticated message transformation (or mapping) tools which allow programmers to specify transformation rules applicable to a simple GUI drag-and-drop operation.
