【Abstract】 Transaction is one of the key technologies whether Web Services can be applied to e-business applications.Transaction technologies for Web Services have to provide the abilities to coordinate short-lived and long-lived transactions.This paper proposes a Web Services transaction model,which can simultaneously handle Atomic transaction and Cohesion transaction,and researches corresponding coordination algorithms,state conversion and recovery mechanisms.Cohesion transaction allows candidates to commit independently,and undoes committed sub-transactions through the compensation transactions so that it can satisfy the requirements for long-lived transaction in Web Services environment,and provide powerful support for commercial web services.更多还原
