Problems solved by technology

When the two databases with data synchronization requirements are far apart, the synchronization delay of traditional database synchronization technology is high, and the synchronization efficiency is low, and due to the high delay, it may also cause the two ends to change the same object. Data conflicts on the database side cause the database to reject correct data modification, resulting in data inconsistencies between the two databases and low reliability

Abstract

The invention provides a remote data synchronization method and device for a database. The remote data synchronization method comprises the steps of acquiring service data containing updated data updating events, generating event versions corresponding to the data updating events, packaging the service data and the event versions into event objects, transmitting the event objects to service applications of an opposite terminal to update an opposite-terminal database according to the service data when the service applications of the opposite terminal determines that the data updating events are effective according to the event versions. The remote data synchronization method and the device achieves rapid and reliable data synchronization.

Description

Technical field [0001] This application relates to database technology, in particular to a method and device for remote data synchronization of a database. Background technique [0002] In database applications, data synchronization between databases deployed in different locations is often involved. When the two ends of the database that have data synchronization requirements are far apart, the traditional database synchronization technology has a high synchronization delay and low synchronization efficiency, and due to the high delay, the two ends may change the same object. Data conflicts on the database side cause the database to reject correct data modification, which results in inconsistent data in the databases at both ends and low reliability. Summary of the invention [0003] In view of this, this application provides a method and device for remote data synchronization of a database to realize fast and reliable data synchronization. [0004] Specifically, this application...
