| 摘 要： | 为了实现位于由应用网关连接的不同安全等级的2个网络中数据库之间的数据同步，考虑到利用数据库管理系统本身具有的同步机制难以实现，提出了一种新的数据同步方案。结果表明，该方案除了能实现不同安全等级的数据库之间的同步，还考虑到TCP协议的差错漏检情况。设计并实现了数据对帐机制，使得同步数据不一致的概率大大下降。

| Abstract: | In order to realize data synchronization between two databases of two networks with different security levels which are connected by an application gateway, a novel scheme of data synchronization was proposed by taking into account the cases of difficulty to realize data synchronization with the embedded synchronization mechanism of the DBMS. The result shows that the scheme of data synchronization can be used to synchronize two databases of different security levels. Taking into account the cases of undetected errors by TCP and lower protocol stacks, this scheme introduced a novel data emendation mechanism that greatly reduced the probability of data inconsistency between two databases. |
