Due to the E-Commerce is getting more popular，the Workflow Management System is broadly used in the enterprise. Traditional workflow management system always facing problem while integrating with systems outside their enterprise, the rapid development of the Web Service technology solve the problem to communicate with different platform, which also bringing the software development and information integration into a new area. BPEL4WS (Business Process Execution Language For Web Services) is a standard dedicated to Web Service integration, along with process execution engine, which can execute composted web service process automatically. Thought the BPEL4WS solve the communication problem with different platform effectively.
And also provide complex business process flow through service composition, but it lack of the user interaction interface, which is popular in workflow management system.
This thesis will design and implementation a workflow engine, which use a BPEL engine as its run time execution environment, based on the standard defined by the Workflow Management Coalition (WfMC). This thesis has the following major contribution:
Design a Workflow Management System architecture, which follows the specification that defined by WfMC.
Extend the BPEL language, by introducing the human interaction web service interface and execute workflow processes by the BPEL engine.
Implement the standard interface defined by WfMC: the Process Definition Interchange and Workflow Management Application Programming Interface. |
