Abstract

The invention discloses a data query method and device, and a data management system. Wherein, the method includes: detecting whether the target data set in the first database changes at predetermined time intervals, wherein the target data set includes a plurality of target data, the target data is the data information of the target user list, and the target user is the record credit degree Users below the preset level; if it is detected that the target data set in the first database has changed, obtain the data change set, wherein the data change set includes the set of data that has changed in the target data set; use the data change set to update The second database, wherein the second database is a database for querying the data information of the target user list; data query is performed in the second database. The invention solves the technical problems in the related art that the query speed of a large amount of data is slow and reduces user experience.

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. 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, no effective s...
