Abstract:
The present invention relates to the technical field of data processing, and specifically provides a data query method and device, a medium, and a data processing system, aiming at solving the technical problem of quickly and accurately searching data from mass data. For this purpose, according to the method of embodiments of the present invention, a key value pair database is used to store object data, and key value pairs stored in the key value pair database use object identifiers, attribute types, and round hours as keywords and use attribute values, in acquisition times, comprising the round hours and non-round hour times in the acquisition times corresponding to respective attribute values as key values. Upon receiving a data query request, key value pair query is performed on a key value pair database according to an object identifier, an attribute type, and time information in the data query request. Corresponding data can be quickly found according to a round hour and a non-round hour time in a key value pair no matter whether the time information is a time period containing a certain duration or an instantaneous time, thus greatly improving the data query efficiency.
