Internal and external network parallel running system for database merging and method of database merging

Abstract

An internal and external network parallel running system for database merging comprises an internal network database management system, an external network database management system, and an all-weather physical isolation system, wherein the internal network database management system and the external network database management system are isolated from each other by the all-weather physical isolation system, and exchange data by ferrying equipment; an external network database temporary mirroring unit imports external network data in an external network data table of the external network database temporary mirroring unit into an intermediate data table; the intermediate data table merges the imported data in an internal network data table; and transaction-based double rollback error treatment is performed on the intermediate data table and the internal network data table after merging. With the adoption of the method, not only can the correct merging of the data in the data tables be realized, but also the out-of-control data during the date merging can be avoided effectively, and the parallel running of an internal network system and an external network system of the all-weather physical isolation system is ensured.

Description

technical field [0001] The invention relates to database data merging technology, in particular to an all-weather physically isolated internal and external network parallel operation system and a database merging method thereof. Background technique [0002] All-weather physical isolation is a phenomenon caused by many problems such as communication technology limitations, confidentiality requirements, and information security needs. All-weather physical isolation between the internal network system and the external network system (referred to as internal network and external network) cannot communicate at any time, and can only exchange data through file ferry. Obviously, the problem of data merging caused by the parallel operation of two systems that are physically isolated around the clock is often very difficult. Under the strict requirement of all-weather physical isolation, the advanced gatekeeper technology loses its meaning. Users often can only realize data mergin...
