服务流程中的数据流处理

Dataflow Processing in Service Workflow

服务流程需要处理服务之间大量的异构数据的交互,不同的数据流处理方式直接影响了服务流程的执行效率。阐述了服务流程模型中的数据流表示模型、数据映射机制与数据流验证机制,论述了服务流程运行中的数据流调度、数据存储以及传输等数据管理问题,分析了数据流处理在服务流程中的应用情况。最后,结合现有的数据流研究进展,提出了数据流研究的展望。

Service workflow needs to deal with a large number of heterogeneous data interactions between services.Different data processing approaches can directly affect workflow execution efficiency.Some data modeling issues such as dataflow implementation models,data mapping techniques and dataflow validation approaches were firstly presented.Then,several data management topics during workflow execution were discussed,including dataflow schedule,data stora-ge challenges and data transfer challenges.In addition,the current situation of dataflow processing in service workflow was analyzed.Finally,combined with the existing data flow related works,some future research directions of dataflow were pointed out.
