业务流程即服务中的数据映射问题研究

Cascade data mapping to support BPaaS

业务流程系统通常需要通过企业数据库与支撑企业运营的其他系统实现协同工作。现有的工作流系统的数据散布于多处,造成了流程虚拟化的困难。SeGA作为一种以Artifact为中心的业务流程模型,给出一种封装业务流程数据的方法,使业务流程可以作为服务实现所谓的BPaaS。为了保持SeGA与企业数据库(EDB)间的数据一致性,采用级联数据映射的方法,借助业务实体模版和流程数据库模板建立了两者的映射。分析了这种映射的可行性条件,论述了映射的各种工具以及业务实体和EDB的同步机制。针对真实房产管理应用场景,结合开发的原型系统检验了该方法的有效性。

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.
