Problems solved by technology

[0005] In order to solve the problem in the prior art, when there are many types of data attributes, the number of pre-established inverted index tables is very large, causing the inverted index tables to occupy a large amount of storage resources, and the establishment process of the inverted index table and When grouping, the process of querying the corresponding inverted index table consumes a large amount of processing resources. Embodiments of the present invention provide a data grouping method and device. The technical solution is as follows:

Abstract

The invention relates to a method for grouping data and belongs to the technical field of data query. The method comprises the following steps: while grouping target data, querying each data attribute identifying set (identifying set including each attribute value) in a data set corresponding to n data attributes, performing intersection operation on the identifying set of the target data and the identifying set for each data tribute in n data attributes, and then acquiring a grouping result for grouping the target data according to n data attributes on the basis of an operation result. The requirement for grouping the data in a database according to any category number and data attribute of the category can be met by only setting the identifying set for each data attribute corresponding to the data set, so that the storage resource occupation of the preset information can be greatly reduced, and the treating resource consumption in the processes of generating and querying the preset information can be reduced.

Description

technical field [0001] The invention relates to the technical field of data query, in particular to a data grouping method and device. Background technique [0002] In some databases, each data contains a variety of different data attributes, and the data can be grouped according to at least two of the data attributes, so as to provide query services related to grouping. Wherein, the data corresponding to the same data group obtained by grouping should have the same values ​​of at least two data attributes. [0003] In the prior art, the database management device performs an inverted index on each data in the database according to a combination of at least two data attributes in advance to establish an inverted index table, which includes the combination of the data attributes Each set of attribute values ​​of , and the identification of the data containing the set of attribute values ​​corresponding to each set of attribute values. When it is necessary to group the above...
