302Implementing and Administering WebSphere Business Integration Server V4.2.2
8.1 Overview
Now that the order is created in the order management system, you can order
the individual parts.
The purpose of the message flow is to accept the order message from the
workflow and then to split out every part of the order into a separate message.
These separate messages flow to another flow that simulates an external
application sending order response messages.
To do this, the message flow makes use of the aggregation nodes that are part of
WebSphere BI Message Broker. The message flow waits for all of the answers to
return from the simulation flow and combines all answers into one message,
formatted according to WebSphere MQ Workflow rules.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.
