摘要： 工作流高级事务模型因结构过于复杂，或者实现起来过于困难，很难应用到实际的工作流系统中。该文以Saga模型为基础，结合成熟的对象事务服务技术，并应用多agent技术对结合OTS模型的Saga模型进行优化，提出并实现了一种切实可行的高级事务模型Esaga，为Saga模型增加了分布式事务支持，很大程度上弥补了Saga模型的不足。

Abstract: Most of advanced transaction models can not be employed in realistic workflow systems, because of their complicated structures or difficulties in implementation. This paper presents Esaga (extended Saga), a new advanced transaction model, which is based on Saga model and mixed with OTS technology and improved by multi-agent. Esaga model, which supports the distributed environment, offset the shortage of Saga in deep extent.

Key words: advanced transaction model, object transaction service(OTS), Saga, agent
