The client sends the Guest Itinerary for reservation processing. The business process
enumerates the travel preferences. These include the travel date, food preference,
seating preference, and information like maximum travel stop overs. It then finds a
suitable airline that matches the customer's preference. The above business process
does an availability check on partner airlines based on the travel preference. It then
updates the itinerary and sends it back to the client. Finally the airline's DBs are
synced to reflect the current seat status.
Note that NorthAir Web Service and SouthAir Web Service work independently of
each other and need not know that they are part of a business process or that they
are being orchestrated. This kind of process can be implemented in BPEL easily.
Throughout Chapter 10, we will discuss various business processes examples.
