The following is the high level overview of the
orchestration.
1.
There are two incoming messages, Book and Publisher. Since a Parallel
shape is used, both messages would need to arrive to process and complete the
Orchestration.
2.
An updategram is created by mapping the Book and Publisher messages.
3.
The Map is called in the Transform shape.
4.
Notice that the send shape is used to transmit the updategram XML to the
SQL Send port.
5.
Observe the database tables and you would notice that two rows would
have been inserted in the tables (one in each table).
