Abstract

The embodiment of the invention discloses a method and a device for indexing data. According to the method and the device for indexing data provided by the embodiment of the invention, N unidimensional indexes are obtained according to N dimensions, wherein the N unidimensional indexes are corresponding to the N dimensions and are independent of each other, and whether address records of the N independent unidimensional indexes have intersection is judged, so that data oriented by the address records corresponding to the intersection are obtained as index target data. According to the method and the device for indexing data, the problem that the unidimensional indexing technology can not meet the requirements on combination query and multidimensional analysis of multidimensional indexes is solved, and the count values of the label number of flag bits corresponding to the address records of the N unidimensional indexes are determined, so that the requirements on speed of multidimensional analysis are easily and conveniently satisfied, the indexing complexity is reduced, and the performance for accurately indexing data is improved.

Description

technical field [0001] The invention relates to the technical field of data indexing, in particular to a data indexing method and device. Background technique [0002] With the development of business intelligence (Business Intelligence), rapid statistics and indexing of massive data are required in various fields such as telecom service quality management, network performance management, and Internet application analysis. High requirements for fast storage, statistics, and indexing. [0003] At present, the data indexing technology of the distributed storage system (Hadoop Database) is used to solve the indexing problem of massive data. The index data is mainly established by dividing the massive data into regions, and stored in different domain storages in the form of column storage. Dimensional indexing technology indexes data. The single-dimensional index technology based on the data of the distributed storage system (Hadoop Database) can only create limited index data...
