Distributed data synchronization system and method

Abstract

The invention relates to the technical field of database application, and discloses a distributed data synchronization system and method. In the invention, the distributed data synchronization system comprises a master server station and a plurality of sub server stations; all the sub server stations are respectively in communication connection with the master server station; the master server station is a data sending end; the sub server stations are data receiving ends; or, the master server station is the data receiving end; the sub server stations are data sending ends; the distributed data synchronization method comprises the following steps that the data sending end sends all data to be synchronized to the data receiving end in real time according to a pre-configured data format, wherein all the data to be synchronized include a plurality of data items; the data receiving end receives data from the data sending end in real time; the original data to be synchronized are covered by the received data; therefore, the data are updated in time; pressure balance is realized; requirements to the server are reduced; and the cost investment of the server is reduced.

Description

technical field [0001] The invention relates to the technical field of database applications, in particular to a distributed data synchronization system and method. Background technique [0002] Different branches of large enterprises are distributed in different regions, and modern enterprises require unified information management. Based on this requirement, there are usually two implementation schemes at present. One is the single database method, that is, the head office and branches use the same database; the other is the multi-database method, that is, each branch uses its own independent database, and then the data in the branch database and the data in the head office database are combined Synchronize. [0003] Among them, the advantage of the single database method is that the data is timely, but the disadvantage is that once there is a problem with the public network, the system will not be able to be used normally, and all performance pressures are concentrated ...

[0003] Among them, the advantage of the single database method is that the data is timely, but the disadvantage is that once there is a problem with the public network, the system will not be able to be used normally, and all the performance pressure is concentrated on the head office.

The advantage of the multi-database method is that it is not affected by the public network, and the performance pressure is distributed among the branches. The disadvantage is that the head office cannot know the data of the branches in real time, and the data of the head office and the branches are synchronized on the public network and face the risk of data leakage.
