Data synchronization method and system

Abstract

The invention provides a data synchronization method and system. According to the method, a client side generates a corresponding updated file, a server updates a database at a server side through the mode that the updated file is read, in this way, even if a terminal where the client side is installed does not establish connection to a server, the database at the server side can be updated under the condition that a user can upload the updated file to the server through other network connections or modes, and for example, the updated file is copied to a movable storage device and transmitted to the server through other internet surfing terminals in an environment with a stable network connection. According to the method and system, under the condition that the terminal where the client side is installed is not connected to the corresponding server, data updated by the client side can be allowed to be synchronized with the server.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data synchronization method and system. Background technique [0002] With the vigorous development of the information construction of the State Grid, the construction of electric power infrastructure projects has also entered the information age. However, the power infrastructure project itself has insurmountable characteristics, that is, wide coverage, remote construction site, poor or even no network signal at the construction site, which makes it difficult or impossible for the construction site to access and deploy urban project management through the Internet system, so it is necessary to deploy a stand-alone version of the client at the construction site to solve the problem of data collection and entry on the construction site, thus solving the problem of data entry on the construction site. [0003] After data entry, the data on the stand-alone version needs to be s...

Problems solved by technology

[0004] However, the wireless network card is prone to unstable network connection when synchronizing data across operators and servers deployed in urban areas. Synchronization is successful, and partial data synchronization cannot be rolled back as a whole. In addition, if the amount of data generated by the stand-alone client is large, or the wireless signal is unstable, it will take a long time or more time during the data synchronization process. Data traffic, resulting in more wireless Internet access fees
