Embodiment Construction

[0016] figure 1 It is a schematic structural diagram of the specific implementation of the method for data synchronization between different databases under the condition of physical isolation in the present invention. During the operation, the business data in the source database of the external network is synchronized to the target database of the internal network. The direction of the arrow in the figure is the business data flow direction.

[0017] figure 2 It is a complete flow chart of operation when the present invention is implemented, and the concrete operation steps are:

[0018] 1. Standardize the content and format of the business data to be transmitted in the source database according to the provisions of the metadata table of the external network and export them to the USB flash drive;

[0019] 2. The business data in the U disk is imported into the intermediate database;

[0020] 3. Set the intranet metadata table according to the final needs of users, verif...

Abstract

The invention provides a method for synchronizing data between different databases under a physical isolating condition in order to ensure the stability of inputting data to a target database. Through building a temporary middle database inside an intranet, a synchronous buffering is realized between different network environmental databases, at the same time, the requirements of synchronization and the completeness of the data can be satisfied, and the flexibility of the operation is improved through designing a metadata table. The method has a high demand on safety and needs the intranet and an outer net to be isolated physically; the data with large data quantity can work stably in the different databases during synchronizing through the method.

Description

technical field [0001] The invention belongs to a method for synchronizing data between databases, in particular to a method for synchronizing data between different databases under the condition of physical isolation. Background technique [0002] At present, data synchronization between existing databases is carried out in an online environment, but data synchronization between different databases with high security requirements and physical isolation between internal and external networks generally uses mobile media to copy data files, and then directly through The command tools provided by the database are imported. If an error occurs in the data import operation directly through the command tool, the entire data file needs to be re-imported, and the import process is usually carried out during a time period with less business volume, in order to avoid the abnormality of the target database that may be caused by operation errors and damage the stability sexual demands. ...
