一种基于AOSD的工作流管理系统的实现

采用面向方面软件开发方法建立事务工作流管理系统的软件体系结构。通过提取工作流应用的业务流程业务活动、参业者和事务这四个关注点，利用面向方面的软件开发方法实现并独立封装事务工作流的需求关注，并对这些关注的实现进编织生成事务工作流应用程序，解决不同工作流程之间、不同事务之间信息交换和协同工作，在确保系统执行状态正确的基础上，降低了工作流应用关注间的耦合性，增强了事务管理柔性管理能力。

An Implementation of Transactional WfMS Based on AOSD

An Aspect-Oriented software architecture is presented based on Oriented Aspect Software Development. There are four concerns, which are business process, activity, participant and transaction, are extracted from workflow application. All workflow concerns are implemented independently, and then they are weaved into a workflow application system. Different business processes can cooperate and exchange data, and do transactions to do so. It can guarantee workflow application is correct in running-time, and reduce the coupling among workflow application concerns. The workflow management is flexible.
