Abstract: Based on the analysis of the basic concepts and features of workflow and business object, etc., scheduling algorithms for workflow engine and data flow of inter-activity were proposed. By borrowing process instance data produced by workflow engine, control scope and ability of workflow engine were extended to man-machine interface. This mechanism extended the core ideology of traditional workflow engine, so that interactions among data could be processed under control. Operation efficiency was improved by changing the interaction pattern from manual search to automatic retrieval.

Key words: workflow, data flow, scheduling, business object, data interaction
