Business Process Execution Language (BPEL)

Need for Business Process
• Developing the web services and exposing the functionality is not sufficient • We also need a way to orchestrate these functionality in the right order • Example:
> Concert ticket purchase Web service has 3

operations, which need to be performed in the following order > Getting a price quote > Purchase a ticket > Confirmation and cancellation
