Chapter 7 Working with Business Process Models

Generating an orchestration BPM from an orchestration BPM

You can generate an orchestration BPM from another orchestration BPM in order to execute your BPM in a specific application or to use a language standard format. Most of the time you will perform the following types of generation:

• Reversed BPEL file > Sybase WorkSpace Business Process BPM
• SOA > Sybase WorkSpace Business Process or BPEL

The following transformations are performed when you generate a Sybase WorkSpace Business Process BPM from an orchestration BPM (SOA or any of the BPEL languages):

• Operation - Each language can restrict the type of operations that can be attached to a process. In Sybase WorkSpace Business Process, the following operation types are supported:
  
  
  • One-Way
  • Request-Response operation
• Top-level process - In Sybase WorkSpace Business Process, the top-level process is not supported. The flow chart is moved to the top-level diagram and must contain at least a start, a process and an end. In case of multiple top-level processes, these are all associated with the same start and end.
• Package - In Sybase WorkSpace Business Process, packages are not supported, as the model can contain only one process.
• Additional transformations - The following additional transformations are performed from a BPEL BPM to a Sybase WorkSpace Business Process BPM:

  BPEL	WorkSpace Business Process
  Flow with <<link>> stereotype.	Not supported.
  Single process with multiple output flows.	Split between the single process and the multiple output flows.
  Single process with multiple input flows.	Join between the single process and the multiple input flows.
  Start with multiple output flows.	Choice between the start and the multiple output flows.
  End with multiple input flows.	Join between the end and the multiple input flows.
  "Receive request and reply" action type for operation.	"Receive request" action type for operation.
  Switch decision.	SingleRule decision with "If-Then-Else" expression.
  Event handler (flow chart of processes to handle an event).	Composite process (containing the flow chart) with appropriate event handler stereotype.
