Chapter 9 Building an Executable BPM: Managing Data and Choreography

Processes (Executable BPM)

A process in an executable BPM can have the following roles:

A global service that does not belong to a graph but describes its behavior in a sub-graph called composite process. It corresponds to the top-level process

For more information about top-level processes, see section Understanding top-level diagrams and top-level processes in an executable BPM in chapter Building an Executable BPM: Working with Service Description Objects processes.

For more information about composite processes, see section Defining composite processes in chapter Building an Analysis Business Process Model.
A composite process within a top-level process in order to restrict the scope or the visibility of some objects
An atomic action called activity. Activities are carried out within the composite process, they interact with a service, manipulate the passing data and handle exceptions. You must specify their implementation

A business process mainly uses the following activities to interact with Web services:

Activity type	Description
Invoke operation	Used by a business process to make invocations to Web services provided by partners. The business process sends One-Way or Request-Response operations
Receive request	Used by a business process to provide services to its partners. The business process receives the invocation of Notification or Solicit-Response operations triggered by partners
Throw activity	Used by a business process to cause a specific fault to occur to abort a transaction, activity or process. The business process throws a Fault event
Compensate activity	Used by a business process to cancel the actions performed by an already terminated process The business process sends a Compensation event
Wait activity	Used by a business process to pause the process for a specified time. The business process sends a Timer event

For more information about the different types of operations, see section Input/Output tab of the operation in chapter Building an Executable BPM: Working with Service Description Objects.
