Problems solved by technology

[0002] In the prior art, for a comprehensive database system, it is very complicated to query data. The problem is that the comprehensive database is confusing when storing data and indexing, and cannot search in an orderly manner according to the needs of users. Therefore, the efficiency of the existing data query method is low, and the query speed is relatively long.

Abstract

The present invention discloses a data query system and method, and is applicable to the field of database technologies. The system comprises a time setting unit, a first indexing unit, a second indexing unit and an index combination unit. The method comprises: step S1, acquiring query time associated with an externally inputted query request; S2, searching to obtain all data stored in a data storage system at the query time, and associating the data to a preset index parent node; step S3, associating the all data stored at the query time with different index child nodes of the index parent node according to values; and step S4, integrating the index parent node and all the corresponding index child nodes to form a tree structure index used for data query performed by a user. The above technical scheme has the advantages of improving data query efficiency and shortening data query time.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a data query system and method. Background technique [0002] In the prior art, for a comprehensive database system, it is very complicated to query data. The problem is that the comprehensive database is confusing when storing data and indexing, and cannot search in an orderly manner according to the needs of users. Therefore, the efficiency of the existing data query method is low, and the query speed is relatively long. Contents of the invention [0003] According to the problems existing in the prior art, a technical solution of a data query system and method is now provided, aiming at improving the efficiency of data query and shortening the time of data query. [0004] The above-mentioned technical solutions specifically include: [0005] A data query system, wherein, connected to a data storage system, further comprising: [0006] a time setting unit, configured to ...
