摘要: 为提高成批处理工作流执行的自动化程度,建立了可描述活动分组实例与活动分组执行实例间投影、合并、分发与拆分等数据交互操作的活动成批处理数据模型;通过在成批处理调度引擎中增加一个数据管理组件,并扩展引擎的调度控制算法,提出了一种对成批处理工作流中数据流进行管理与控制的机制,解决了原有引擎不能对数据流进行调度控制的问题。最后通过实例验证了所提方法的可行性。

Abstract: To improve the execution automaticity of batch processing workflow, a data model for activity's batch processing was proposed. It described the data interaction operations such as projection, composition, distribution and decomposition. By introducing a new data management component in batch processing scheduling engine, and extending the engine's scheduling control algorithm, a control and management mechanism of data flows in batch processing workflow was presented. It solved the scheduling and control problem of data flows in the original engine. Finally, the mechanism was validated by an application example.

Key words: workflow, batch processing, data flow, control, automaticity
