Abstract

The invention discloses a peer-to-peer network-based heterogeneous database synchronization method. The method is realized based on a heterogeneous database synchronization device composed of routing nodes and a global proxy server. The method comprises the steps of detecting the information charging condition of a database, feeding back the information changing condition to the global proxy server, broadcasting the changed information to the routing proxies of all nodes by the global proxy server, updating the resource information of each node, recording the timestamp of the updated information, updating the recorded timestamp in a block chain, updating the proxy synchronization state of each node, recording the timestamp thereof and the-be-changed information, and feeding back the updating state to a global proxy. According to the invention, through the decentration process, the self-management of each node is realized. Therefore, the reliability and the usability of database synchronization are greatly improved. The above method is conducted based on the block chain technology and enables the complete data exchange record. Meanwhile, the problem in the prior art that the data exchange in the traditional goal-centered approach cannot be traced is solved.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method for synchronizing heterogeneous databases based on a peer-to-peer network. Background technique [0002] The development of information technology in Guanmin is changing with each passing day. Many information systems were built in different periods and designed by different manufacturers, which makes the platforms of these systems often show heterogeneity, resulting in data inconsistency. If data information is not effectively shared, these independent data systems will become "information islands"; in addition, with the vigorous development of enterprise business and the continuous improvement of informatization, the data exchange between various application systems is also increasingly Frequently, it will bring such a problem: the demand for data exchange and data synchronization between different platforms and data sources in different formats is bec...
