Workflow data patterns based analysis of Xinpai-driven model

Data flow is a guarantee of control flow which can implement correctly in workflow management system. Processing and tempering data flow has been becoming more important. Workflow data patterns firstly use pattern-based to summarize 40 patterns for the characters and implement of data which is in data perspective in workflow. Xinpai-driven workflow computation model which was developed by software engineering institute of Northwest University is theoretical basis of workflow management system which depends on Web. In this paper, we will analyze the expressive power and suitability of Xinpai-driven model for data flow modeling in workflow. Final complete the expansion of Xinpai-driven model in data perspective.
