Problems solved by technology

Since this synchronization method loses the transaction information when it is initially entered into the table, the data corresponding to the difference of all transactions must be synchronized during the synchronization process, otherwise the integrity of the transaction cannot be guaranteed
[0004] This synchronization method is not only cumbersome, but if there is a lot of synchronization data, the database transaction will be too long, which will not only occupy more system resources, but also may cause synchronization failure

Abstract

The invention relates to the technical field of data synchronization, and discloses a database synchronization method. The method comprises the following steps of: capturing the variation information of the data in a source database and the affairs corresponding to the data variation in real time, and storing the captured variation information and the affairs in a middle database; determining a target database needed to be synchronized, according to the variation information stored in the middle database; converting the variation information into the target data corresponding to the target database; and synchronously updating all the target data corresponding to the same affair to the target database. With the database synchronization method and the system thereof, the data synchronization of different types of databases and the data synchronization between heterogeneous data tables are implemented, consumption of system resource in the synchronization process is reduced, and the reliability of the synchronization process is ensured.

Description

technical field [0001] The present invention relates to the technical field of data synchronization, and more specifically, to a database synchronization method and system. Background technique [0002] In the production and operation process of an enterprise, there are often multiple systems, and these systems need to cooperate with each other, and some data needs to be shared among these systems, so it is necessary to keep these shared data synchronized among different systems. [0003] In the prior art, due to differences in different systems and different functions, the physical structures of the databases in each system are not completely consistent. In order to synchronize these shared data, it is usually necessary to write a synchronization program for each system. In the process of data synchronization, the synchronization program converts the data in the source table, compares the converted data with the data in the target table, and then incrementally synchronizes ...
