Abstract

The embodiment of the invention provides a data synchronizing method and device and a server cluster. On the one hand, the data synchronizing method provided by the embodiment of the invention comprises the following steps: monitoring source databases according to monitoring ways corresponding to the source databases in order to obtain data change information of the source databases; processing the data change information according target databases which are about to synchronize the data change information in order to obtain synchronization information corresponding to the target databases; and transmitting the synchronization information to the target databases in response to a synchronization command. Through adoption of the data synchronizing method and device and the server cluster, data synchronization from a plurality of different types of source databases to different types of target databases is realized; one target database of the same type used for synchronizing does not need to be set for each source database needing to be synchronized; the storage cost is lowered; the storage efficiency is increased; and the problems of high storage cost and low storage efficiency in a distributed data system including a large quantity of different types of databases are solved.

Description

[0001] 【Technical field】 [0002] The solution relates to the communication field, in particular to a wireless search method, device and server cluster. [0003] 【Background technique】 [0004] In the information age, all walks of life use databases to manage industry information. As the basic system for the operation and management of the railway industry, the railway information system also uses databases to store and manage relevant information. [0005] Railway information system is a huge and complex system, including operation system, marketing system, transaction system and many other systems. The railway information system relies on the three-tier business structure of the railway company, railway bureau and station, and is a distributed system related to geographical location. [0006] At present, the databases of railway information systems are generally dominated by commercial databases Oracle and Sybase. With the continuous improvement of the country's requiremen...
