Web service的事务协调框架研究与实现

提出并实现了一种Web服务的事务协调框架，DTCF（Distributed Transaction Coordination Framework）。该模型基于嵌套事务模型和协调思想，将局部事务的实现细节进行封装，不同局部事务可采用不同的并发控制和恢复技术，而对全局事务则采用完全分布的管理机制进行管理。DTCF是一种可重用的框架，实验结果表明其可用性。

Research and implementation of transaction coordination framework

Coordination is a basic concept of distributed computing and Web services transaction processing.This paper puts forward and implements a distributed transaction coordination framework.The model has a fully decentralized mechanism for global transaction management and concurrency control，and different implementation details including different concurrency control and recovery strategy are encapsulated in local transaction model.The prototype system of this model，named as DTCF（Distributed Transaction Coordination Framework），provides a reusable framework of developing distributed transactional application.Testing results prove that this framework is efficient to develop distributed transactional application.
