After reading the article "A First Look at SQL Server 2005 Service Broker"
by Roger Wolter (http://www.microsoft.com/indonesia/msdn/sqlsvcbroker.asp),
I have a simple question to the scenario one in that article,

Because the Figures in the original article is lost, I put one on my
machine, link the following link,
http://www.liwasoft.com/Others/FirstLookat.htm#Scenarios

My Question is about the scenario one, Order Entry.

According to the original article, "As the Order Entry service inserts the
order headers and order lines into the database, it queues messages to the
billing, shipping, inventory, and credit limit services to finish processing
the order."

I Found that there are not only four arrow line from Order Entry Service to
the other four Queues (green lines), but also four arrow line from Other
Services to the Order Entry Queue (pink lines).

I don't understand why there are four pink lines there.

In my thought, Order Entry Queue is a queue to append order entry messages,
not a queue for append an approved messages.  If the Order Entry Queue do
accept the approved messages, Service Broker would activate more new Queue
Readers to process that messages.  The original Queue Reader would not get
the approved messages, but the new ones would.

Am I right?
