Abstract

The invention discloses a data inquiring method and device. The data inquiring method includes receiving an inquiring instruction which is an instruction used for indicating inquiry of data from a preset database in which multidimensional data are stored, wherein the multidimensional data are stored in a data table in the preset database, the inquiring instruction includes a first dimension and a second dimension which are any two different dimensions in multiple dimensions; acquiring the first dimension and the second dimension from the inquiring instruction; inquiring data corresponding to the first dimension and the second dimension from the preset database; displaying the data acquired by inquiring and corresponding to the first dimension and the second dimension. By the data inquiring method, the problem of low efficiency in inquiring multidimensionally related data is solved, so that effect of improving effect of inquiring the multidimensionally related data is realized.

Description

technical field [0001] The invention relates to the field of databases, in particular to a data query method and device. Background technique [0002] The current database design follows the third normal form when the amount of data is relatively small, which effectively avoids data redundancy, saves storage space, and reduces the cost of redundant maintenance. For example: designing a database for storing information in three associated dimensions of apples, fruit trees and orchards, a typical design such as figure 1 As shown, three data tables of orchard table, fruit tree table and apple table are established to store the information of orchard, fruit tree and apple respectively. The apple table establishes the relationship between apples and the fruit trees they belong to through the fruit tree identification. Users usually need to analyze and count the data in the database. Taking the above-mentioned orchard as an example, when analyzing the apple production in a certa...
