Abstract: Aiming at the problem that the existing workflow system were scatted to hard realize virtualization,a method of encapsulated business process data was given by SeGA as an Artifact-centric business process model,which became a promising enabler to approaching Business Process-as-a-Service (BPaaS).It naturally emerged the challenge how to maintain the data consistency between SeGA instance and enterprise database.By using the method of cascade data mapping,the mapping between business entities template and Enterprise-wised Database (EDB) template was established,and the feasibility of such a mapping was analyzed.The mechanisms to synchronizing data between business entities and EDB were discussed.The proposed method was validated by developing a prototype against real scenarios in real estate settings.

Key words: Artifact-centric business process modeling, business process as a service, data mapping, data consistency
