Abstract

The invention discloses a database synchronization method and device, electronic equipment and a computer storage medium. The database synchronization method comprises the steps: in a first database and a second database, extracting information of each database object according to an information model of each database object, and obtaining an information set of each database object, wherein the information model of each type of database object is used for representing an information structure of the corresponding type of database object; comparing the information set of each database object in the first database with the information set of each database object in the second database, and generating an incremental script for synchronizing the first database based on the second database according to the difference obtained by comparison; executing the delta script for the first database. According to the embodiment of the invention, the problem of synchronization failure caused by the fact that all modification operations are not completely recorded when incremental synchronization is executed through a method for recording the modification operations can be solved, and the technical effect of more stable database synchronization can be realized.

Description

technical field [0001] The invention belongs to the technical field of databases, and in particular relates to a database synchronization method, device, electronic equipment and computer storage medium. Background technique [0002] When performing database synchronization between the source database and the target database, incremental synchronization can be used. Incremental synchronization is to modify the source database for the difference between the source database and the target database, so that the source database is synchronized to be consistent with the target database. [0003] In order to achieve incremental synchronization, a method is provided in the related technology. A service is hung on the server where the target database is located to record each modification operation of the target database. When synchronizing the source database, according to the A modify operation performs the same modification operation on the source database. [0004] However, if...
