Multidimensional data permission query method and device

Abstract

The invention discloses an authority query method and device of multi-dimensional data, and belongs to the technical field of computers. The method comprises the following steps: acquiring the multi-dimensional data of which the authority is to be queried; acquiring a type bitmap of the multi-dimensional data according to the data type information of each dimension of data; determining a combined subtype bitmap of the multi-dimensional data according to the type bitmap of the multi-dimensional data and the type bitmap in previously acquired authority index data, and querying authority index information corresponding to the combined subtype bitmap in the authority index information; querying corresponding authority information from the previously acquired authority data according to the authority index information corresponding to the combined subtype bitmap, and determining the authority of the multi-dimensional data according to the queried authority information. By introducing the type bitmap and the authority index information mechanism, the authority query of the multi-dimensional data is realized, so complex functional operation is not required in the entire query process; compared with a mode of querying authority by using a hash table, the authority query efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multidimensional data authority query method and device. Background technique [0002] With the advent of the information age, social network products are becoming more and more popular, and people can pay more attention to more and more things by publishing information through these social network products. However, it is inevitable that there will be some negative information such as pornographic information, spam advertisements, rumors, phishing website links, etc. in the information released through the social platform where the social network product is located. In order to maintain the social network environment, it is necessary to control the authority of IP addresses, instant messaging numbers and other data that publish information, so as to reduce the release of negative information. Among them, the IP address or the instant messaging number are single-dimensional ...

AI Technical Summary

Problems solved by technology

[0005] Because a large number of hash operations are required to query the permissions of multi-dimensional data through the hash table, the process of querying permissions is cumbersome, especially when the multi-dimensional data to be queried has many dimensions, not only the query process is cumbersome, but also the query process consumes a lot of time. time is also longer

Therefore, the permission query method for multidimensional data provided by the prior art has low query efficiency
