Abstract: 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.
