摘要
根据项目特点,建立了适合ASP平台的基于协调理论和反馈机制的扩展活动网络模型,采用XML模式的XPDL规范实现过程定义;然后通过DOM解析XML数据文档和J2EE的技术支持实现了系统的轻量级工作流引擎。详细介绍了系统实现中解决的两个关键问题:事务型操作的处理和并发控制,并提出了基于优先级的锁绑定机制。
According to the project characteristics, an expansion activity network model suitable for ASP platform had been set up. The model was on the basis of coordinate theory and feedback mechanism, adopted XPDL norm of XML mode to realize the process definition. Then the system analyzed the XML data documents through DOM and implemented the lightweight workflow engine with the support of J2EE technology. This paper introduced the two key problems solved by the system： transactional operation and concurrent control, and proposed the lock tie mechanism based on PRI.
