Data exchange system and method thereof

Abstract

The invention discloses a data exchange system and a method thereof. The system comprises a first database server, a second database server, a first preset server, a second preset server, a first unidirectional gap and a second unidirectional gap. The first presser server acquires data information of a first data sheet and first sheet structure information from the first database server, and receives second sheet structure information from a second data sheet of the second preset server through the second unidirectional gap, and performs data information mapping according to a preset field mapping relation between the first data sheet and the second data sheet, the first sheet structure information and the second sheet structure information, thereby obtaining target data, and transmittingtarget data to the second preset server through the first unidirectional gap. The second preset server receives the target data through the first unidirectional gap and loads to the second data sheetof the second database server, and transmits the target data loading result to the first preset server through the second unidirectional gap.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a data interaction system and method. Background technique [0002] In some secret-related units, especially the public security system, the data network is generally divided into internal network and external network. Among them, the internal network is a local area network, which is generally a confidential network, and the external network is the Internet / wide area network, and the internal network and external network are physically isolated from each other. In practical applications, there are often scenarios where computers on the external network need to obtain data from databases on the internal network, or computers on the internal network want to obtain data from databases on the external network. And this involves the problem of database data exchange between different networks. At present, there is no solution in the prior art to realize the exchange of...
