Abstract: Business-driven development favors the construction of a business process by different business-development staffers.In order to obtain a standard reference process to consolidate these variants,it is necessary to detect and resolve differences between data aware processes.Existing approaches focus on detection and resolution of differences between process models with relying on a change log at the level of control flow.However,few methods can study the problem of differences between data aware processes.Based on program dependence graphs and correspondences,a novel approach was proposed to detect and resolve differences by comparing before and after modified data aware processes.It builds a hierarchical change log and meets requirements of user-friendliness.

Key words: Data aware processes,Differences,Program dependence graphs,Hierarchical change log
