Process Language Definition Reference

The chapters in this part provide information specific to the business process languages supported by PowerDesigner.

• Business Process Modeling Notation (BPMN)
  Business Process Modeling Notation (BPMN) 2.0 from the Object Management Group (OMG) is a standardized graphical notation for modeling business processes. It is intended to provide a notation that is readily understandable by all business users (including business analysts, technical developers, and those who will manage and monitor the processes after implementation) and to create a standardized bridge between business process design and XML-based business execution languages, such as BPEL4WS and Sybase Integration Orchestrator.
• Data Flow Diagram (DFD)
  The Data Flow Diagram (DFD) is a graphical representation of the flow of data through an information system. It enables you to represent the processes in your information system from the viewpoint of data. The DFD lets you visualize how the system operates, what the system accomplishes and how it will be implemented, when it is refined with further specification.
• Service Oriented Architecture (SOA)
  SOA is a logical orchestration process language that allows you to orchestrate your processes without being linked to any platform or language. It belongs to the Service Orchestration family.
• BPEL4WS and WS-BPEL
  BPEL4WS 1.1 (Business Process Execution Language for Web Services) and its successor WS-BPEL 2.0 (Web Services for Business Process Execution Language) are business process orchestration standards which let you describe your business processes under the form of Web services, and specify how they are connected to each other to accomplish specific tasks. PowerDesigner supports modeling for BPEL4WS 1.1 and WS-BPEL 2.0 and higher, including round-trip engineering.
• Sybase WorkSpace
  You define a BPM with the Sybase WorkSpace Business Process language when you want to design business processes and implement them using Business Process Service in Sybase WorkSpace.
• Electronic Business XML (EbXML)
  A collaborative BPM is used to design Business-to Business exchange. It displays the exchange of messages between partners in top-level processes, each of which can be decomposed into a choreography that represents the sequence of message exchanges. PowerDesigner supports ebXML BPSS v1.01 and v1.04.
