为了提高各类冶金数据库研究安全性,与互联网物理断开的内部网络成为这些数据库存放的主要网络环境。在对外发布共享的业务需求时,需要在互联网上放置一个冶金数据库作为安全网络上数据库的子集(部分内容的数据库),用于把可公开的相关数据发布出来。为了在两个没有物理连接网络间把数据库的数据进行单向或双向的同步,我们设计了一个安全数据摆渡机制。该设备同时连接到两个网络,但内部并没有任何的物理连接,它的作用就是同时只连接一个网络,把需要传输的数据取走和传送到另外一个网络来完成一个完整的摆渡过程。这样大大提高了数据库的研究安全性,能提供较好的数据库同步实时性,为整个冶金类数据库提供了另外一种可采用的研究方法。
In order to improve the safety of all kinds of metallurgical database research, the internal network disconnected from the Internet has become the main network environment in which these databases are stored. When publishing shared business needs externally, a metallurgical database needs to be placed on the Internet as a subset of the database on the secure network (part of the content database) for releasable publication of relevant data. In order to unidirectionally or bidirectionally synchronize the database data between two networks that are not physically connected, we have designed a secure data transfer mechanism. The device is connected to two networks at the same time, but it does not have any physical connection internally. Its function is to connect only one network at a time and to take away and transmit the data to be transmitted to another network to complete a complete ferry. This greatly enhances the research security of the database, can provide better real-time database synchronization, and provides an alternative research method for the entire metallurgical database.
