Abstract

Disclosed are a data indexing method and device. The data indexing method and device provided in the embodiments of the present invention acquire, according to N dimensions, N unidimensional indices which correspond to the N dimensions and are independent from one another, and judge whether there is an intersection set of address records contained in the N mutually-independent unidimensional indices corresponding to the dimensions, so as to acquire data to which the corresponding address records of the intersection set point as index target data. The problem that the unidimensional index technology fails to satisfy the need for multidimensional index combined query and multidimensional analysis is solved. Also, by determining the magnitudes of count values of tag number flag bits corresponding to the address records contained in the N unidimensional indices, the speed requirement for multidimensional analysis is satisfied simply and conveniently, the complexity of indexing is reduced, and the data performance of 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...
