摘要
许多传统的工作流管理系统都只提供单层的过程模型,整个业务流程都在一个过程模型中详细描述,使得工作流的模型过于复杂。文中引入工作流的分层模型和嵌套分布执行机制,增强了系统对异构、分布应用的支持力度,提高了对业务流程监视的可视程度,同时也给系统安全机制的实现提供了基础。文中着重讨论其体系结构、工作流模型的建立、工作流引擎和多引擎间的协调机制等。
Only monolayer's process model is offered in many traditional workflow managements.In that model, the whole operation flows are described particularly in one process model, which makes the modeling work much complex. In this paper, layered workflow model and nested,distributed performance mechanism are introduced, which not only buildups the supporting degree of system to isomerous and distributed application, but also improves the dependability of system. In following, the system's structure will be emphasized on, which includes the workflow model,engine of workflow and the cooperation of multi-engines.
