Abstract: Workflow management system(WfMS)has been used to provide a powerful computation environment for integration of different applications and cooperation of different organizations within enterprise.In the current research field of workflow technologies,the distributed workflow engines have gradually caught more and more attentions,and the scalability and flexibility of the whole system are the two critical factors to successful implementation of the distributed workflow system.In this paper,a distributed workflow system with high scalability and high flexibility that runs on different enterprise function domains is introduced.Meanwhile,relevant concept of domain,system infrastructure,implementation of a process instance,and global control mechanism are also presented.
