INFORMATION REPLICATION SYSTEM IN DATABASES Russian patent published in 2019 - IPC G06F16/27 

FIELD: information technology.

SUBSTANCE: invention relates to a data replication system in databases. System is in form of a unit for providing a local network between a first and a second computer, having synchronized databases, as well as a unit for synchronizing operating modes of computers. First and second inputs/outputs of local network providing unit between first and second computers are connected to first and second inputs of first and second computers, respectively, and the first and second inputs/outputs of the computer mode synchronization unit are connected to the second input/output of the first and second computers respectively, as well as unit for comparing data in variable databases, first and second inputs/outputs of which are connected to third inputs/outputs of first and second computers respectively, and the third input/output is connected to the third computer input/output unit synchronization unit output unit, the mismatched fragments selection unit in the variable databases, the first input/output of which is connected to the data comparison unit third input/output in the variable databases, as well as a unit for making changes in variable databases, the first input/output of which is connected to the second input/output of the unit for selecting mismatched fragments in mutable databases, and second and third inputs/outputs are connected to fourth inputs/outputs of first and second computers, respectively.

EFFECT: wider range of technical means used for replication of information in distributed databases.
