Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a file-based database synchronization method, which uses the file method to quickly synchronize from the source database to the target database, and solves the problem of not supporting heterogeneous database synchronization and synchronization during synchronization. Problems that affect the performance of the source database and the database synchronization efficiency is not high

Embodiment Construction

[0029] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0030] A file-based database synchronization method such as figure 1 As shown, the data synchronization tool component is installed on the source database, and the ETL service component (data extraction, transformation and loading service component) is installed on the target database. Quickly synchronize from the source database to the target database.

[0031] The main function of the data synchronization tool component is: to receive the control command of the ETL service component, store the data to be synchronized into the incremental log file and write the incremental log file to the FTP server.

[0032] The main functions of the ETL service component are: to send control commands to the data synchronization tool component to realize the database synchronization control function; to obtain the incremental log file from the FTP server through...

Abstract

The invention relates to a file based database synchronization method, which has the following main technical features that through a mode of installing a data synchronization tool component in a source-end database and installing an ETL (extract transform and load) service component in a target-end database, the control between the ETL service component and the data synchronization tool component is implemented through a protocol, and the synchronization is implemented from the source-end database and the target-end database in a file mode. The method disclosed by the invention is reasonable in design; because the database synchronization is implemented from the source-end database and the target-end database in a file mode, the database data required to be synchronized can be efficiently stored, and in a heterogeneous database and an operating system environment, the synchronous operation of data can be implemented through file analysis, thereby supporting a characteristic of carrying out synchronization on various heterogeneous databases, meanwhile, by using a total synchronization method and an incremental synchronization method, the efficiency of database synchronization is improved.

Description

technical field [0001] The invention belongs to the technical field of database synchronization, in particular to a file-based database synchronization method. Background technique [0002] In a production environment, operating system upgrades or changes, database upgrades, and storage device upgrades can greatly increase the complexity of data migration and synchronization. In the process of data migration, it is often necessary to interrupt the existing business. Such interruption will reduce the service quality and customer satisfaction, and cause huge losses to the enterprise. It can be seen that the synchronization technology of the database is of great significance. [0003] Currently, data synchronization solutions for existing databases mainly include storage replication technology, database replication technology and ETL extraction technology. 1. The storage replication technology is to use the storage array's own disk array to disk array data block replication to...
