摘　　要：提出了一个事务逻辑和业务逻辑完全分离的事务处理模型,简化了客户端的实施,提高了程序的模块化和重用性。研究了该模型的协调算法和状态转换,把自主意识引入参与者,对协调协议进行了扩展,使之更贴近现实的业务场景。通过使用配置文件确定出现异常时的补偿范围和操作,加强了Web服务环境下对业务活动的支持。A transaction handle model was proposed, in which transaction logic was separated from the client＇s business logic, It simplified the implementation of the client and enhanced software modularity and reusability remarkably. The coordination algorithm and state transition were researched, furthermore active consciousness was introduced into participant, and coordination protocols were extracted, to make the handle model closer to the real business situation. By using configuration information, the handle model will know how to do the transaction in expected scope when exception occurs, and it can enhance the support of the business activities in Web Services environment.
