A TRANSACTION MODEL FOR LONG RUNNING BUSINESS PROCESSES*

Abstract: Many business processes in the enterprise applications are both long running and transactional in nature, but currently no transaction model can provide full transaction support for such long running business processes. In this paper, we proposed a new transaction model — PP/T model. It can provide full transaction support for the long running business processes, so that application developers can focus on the business logic, with the underlying platform providing the required transactional semantics. Simulation results show that the model has good performance in processing the long running business processes.
