Abstract

The invention relates to the database application technical field, discloses a distributed data synchronizing system and method. In the invention, the distributed data synchronizing system comprises a server main station and a plurality of server sub-stations; the server main station is a data sender; the server sub-stations are data receivers; or the server main station is the data receiver; the server sub-stations are the data senders; the distributed data synchronizing method comprises following steps that: the data sender detects the states of to-be-synchronized data in real time and only sends data updating logs to the data receivers according to a preset data format; the data receivers receive the data from the data sender in real time; the data items in the data updating logs are assigned to corresponding data items in the data receivers; and therefore, the data of the data receivers and the data sender are consistent. According to the system and the method of the invention, the data are updated timely; the pressure is balanced; the demand to the server is reduced; moreover, the data transmission quantity is low; the communication traffic is saved; and the communication load is relived.

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 ...
