摘要： CORBA的一个重要的服务是OMG定义面向对象的事务服务（OTS），它是对分布事务进行处理的。由于事务处理的重要性，OTS本应该作为ORB的一部分来提高事务处理应用的效率。基于上述考虑，OMG在OTS中提出了interposition技术，文章在方法论的基础上探讨如何采用该技术实现OTS。

Abstract: One of the most important CORBA services defined by OMG is the Object Transaction Service (OTS), which augments the CORBA object model with the notion of distributed transactions. The implementation design of the OTS is critical for the service to be really effective for applications. A good design suggests that the OTS should be part of the ORB (Object Request Broker) itself rather than on top of it like normal CORBA objects. In this paper we highlight the design implementation of OTS and describe how interposition of transaction objects can be achieved.
