摘要
介绍了一个基于消息通知的工作流管理系统,该工作流管理系统以消息通知机制为核心,以消息通知推动流程的运转.工作流模式定义及工作流引擎的设计都围绕消息通知机制进行.用任务表示流程中某个节点中所处理的表单实例,使得表单实例在各个节点的处理过程可以用任务状态表示,工作流引擎通过定时扫描正在处理的各任务状态,控制流程按设定的模式运行.
This pap＇er introduces a workflow management system based on message notification. Message notification mechanism is not only the core of the system but also drives business workflows, thus we design workflow module definition and workflow engine according to it. If we use task to denote a form instance processed in a flow node, the process of the form instance in the flow node can be expressed by task state. Workflow engine scans all tasks under process in a fix period to control the form processed according to workflow module.
