提供一个关于的Java事务处理API（JTA）的高级的概述，以及与分布式事务相关的内容。一个事务处理定义了一个工作逻辑单元，要么彻底成功要么不产生任何结果。 一个分布式事务处理只是一个在两个或更多网络资源上访问和更新数据的事务处理，因此它在那些资源之间必然是等价的。在本文中，我们主要关心的是如何处理关系数据库系统。

-To provide a Java transaction processing on the API (JTA) high-level overview, as well as distributed transaction-related content. A transaction defines a logical unit of work, either complete success or does not produce any results. A distributed transaction processing is only a two or more network resources to access and update data, transaction processing, so it must be among those resources equivalent. In this article, our main concern is how to deal with relational database systems.
