摘要
工作流技术在实现业务流程自动化和企业应用集成等方面有着广泛的应用。基于Web服务的工作流管理系统运行在异构、自治、分布的复杂环境中,其自身的正确性和可靠性成为整个应用软件系统成败的一个关键因素。在工作流管理系统中对事务处理提供支持就是保证系统正确性和可靠性的一个重要方法,文章提出了具有良好事务处理能力的工作流事务原型系统WTBWS。
Workflow technology is applied widely in the domain of implementing business processes automation and enterprise application integration.WfMS （Workflow Management System）that based on Web Service often runs in heterogeneous,autonomous and distributed environments.Therefore,the correctness and reliability of WfMS is of critical importance to workflow system and becomes one of the most causes of the success or failure of the entire application.So the workflow system should have good ability of supporting transaction to ensure the system＇s correctness and reliability. In this paper the research of transaction in WfMS and transaction handling is established on practices.We analyze the existing workflow transaction based on Web Service,and propose a WfMS model WTBWS with transactional feature.
