摘　　要：以扩展事务模型Saga和Flexible为基础,引入可替换事务和平凡事务等事务种类,借用传统事务恢复机制“保存点”的思想,提出了支持分布式工作流应用的可靠事务工作流模型WfSaga,以Java图形操作为基础,设计了图形化建模工具并用基于XML的过程定义语言对模型进行了描述,最后对模型的正确性验证进行了讨论。Based on extended transaction models Saga and Flexible, a reliable transactional workflow model named WfSaga is proposed, which can be adopted in distributed applications. Replaceable transactions and characterless transactions are brought into WfSaga and the traditional transaction idea ＂Savepoints＂ is borrowed. In terms of Java graphics technology, the graphical modeling tools are designed, and the modeling is also described by process-defined language based on XML. At last, the checking of the modeling is discussed.
