| Abstract: | This thesis analysis the transaction in WFMS （Workflow Management System） based on the analysis we conclude what＇s the most important and difficult in the transaction processing in WFMS. In the transaction sphere we provide the rules for transaction recovery to guarantee the workflow process be correct and consistent. This thesis discuss the design and implementation of the transaction expression in Process Definition Subsystem and Enactment Service Subsystem, which is a workflow management system with support of transaction. |
