一种可以取消冲正机制的OLTP软件架构

An OLTP Software Architecture for Getting Rid of Reversal Mechanism

指出了金融联机交易处理系统存在的单边账问题,认为目前普遍采用的冲正机制并非很好的设计方案。提出一套基于双向数据表同步的设计方案，把交易的状态摆到了足够的高度上，提出了状态优先级、状态同步、状态超时以及由状态变化触发的状态转换逻辑的概念， 以及双向表同步协议和双向表同步进程组的概念，给出一套双向表同步协议和双向表同步进程组的设计构思，并举例说明该软件架构的实际应用方法。

This article points out that the widely used reversal mechanism is not a good solution.And proposes a series of two-way table synchronization methods for OLTP systems, and puts forward some important concepts: priority of status, status synchronization,status timeover,status conversion logic triggered by status change,two-way table synchronization protocol, a process group for two-way table synchronization. It presents a set of design for two-way table synchronization protocol and process group also.
