Data inquiry method and device, data management system

Abstract

The invention discloses a data inquiry method and a device, and a data management system. The method comprises the following steps: detecting whether the target data set in the first database is changed or not at predetermined intervals; wherein, the target data set comprises a plurality of target data, the target data is data information of the target user list, and the target user is a user whose record reputation degree is lower than a preset degree; Acquiring a data change set if a change in the target data set in the first database is detected, wherein the data change set comprises a setof data changed in the target data set; Updating a second database with a data change set, wherein the second database is a database for querying data information of a target user list; A data query is performed in the second database. The invention solves the technical problems in the related art that the speed is slow and the sense of user experience is reduced for a large amount of data inquiry.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data query method and device, and a data management system. Background technique [0002] In related technologies, when querying data stored in a database, generally all data stored in the database is queried according to user requirements, and then the queried data is returned to the querying user. This query method, when querying a small amount of data, , can query quickly, but for more data, the query data will be very slow. And in the current data query, the query process can only query a small amount of data. In the case of multiple processes, there will be problems of high concurrent query speed and low query efficiency, which will cause users to use the database. The sense of experience is low. [0003] Aiming at the technical problems in the above-mentioned related technologies that querying a large amount of data is slow and reduces user experience, n...
