Problems solved by technology

Since the mobile database needs to store data copies on the terminal device, when multiple users update the same tuple of the data copy, data conflicts may occur
Existing database vendors provide their own mobile data synchronization components to solve possible data conflicts, but these synchronization components are based on public wireless network environments
[0003] In some special scenarios where wireless network access is limited, such as: high-security sensitive places that need to shield wireless signals, areas where wireless networks are paralyzed due to natural disasters or man-made sabotage, etc., mobile terminals are required for on-site office work and need to communicate with the background The system uploads, downloads, and synchronizes data. At this time, the existing mobile database and its synchronization technology ca

Embodiment Construction

[0043] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0044] The overall structure of the system of the present invention is as figure 1shown. The system as a whole adopts a wired network, so there is no potential safety hazard unique to wireless networks. It is suitable for high-security places where wireless access is restricted, as well as situations where wireless networks are paralyzed due to natural disasters or man-made sabotage, and can also be used for wireless networks. Alternative wired synchronization schemes for synchronization technology, etc.

[0045] Specifically, multiple mobile databases can respectively communicate with the synchronization server through the access point 1 at the location 1 and the ...

Abstract

The invention discloses a mobile database synchronization method and a mobile database synchronization system based on a knowledge base under a network-free environment and provides a traceable synchronization method based on a time stamp and an authority level, which serves as a data conflict solving method; and the data synchronization conflict caused by long-term off-line operation of mobile equipment under the network-free environment can be greatly solved.

Description

technical field [0001] The invention relates to the technical field of mobile database synchronization, in particular to the mobile database synchronization in a non-network environment. The mobile database synchronization can be based on a knowledge base. Background technique [0002] A mobile database refers to a distributed database in a mobile environment. Its data is physically distributed and logically centralized. It is a dynamic distributed database. The mobile database can support mobile users to effectively access the required data and complete data query and transaction processing under the wireless network environment. Since the mobile database needs to store the data copy on the terminal device, when multiple users update the same tuple of the data copy, data conflicts may occur. Existing database vendors all provide their own mobile data synchronization components to solve possible data conflicts, but these synchronization components are all based on public wi...
