Abstract

The invention provides a data comparison method and device. The data comparison method comprises the step: importing data to be compared; preprocessing the data to be compared based on a full-volume relational information database; setting a data comparison rule; comparing the preprocessed data to be compared according to the data comparison rule; outputting a comparison result. According to the data comparison method provided by the embodiment of the invention, the full-volume relational information database is used for preprocessing the data to be compared, then the preprocessed data to be compared is compared according to the set data comparison rule, fragmented data can be used to the maximum degree for data set comparison work, thereby obtaining the required comparison result, and solving the problem that fragmented data and heterogeneous data cannot be compared.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data comparison method and device. Background technique [0002] With the advent of the era of big data, the traditional comparison and collision algorithm can no longer meet the needs of the current data form. The traditional data comparison algorithm is to classify and compare according to the characteristic value of the data itself, and find out the elements that appear together in different data sets. However, if the data of the data source is incomplete, or the data expression has a certain degree of uncertainty, or the data expression dimensions are different, the required conclusion cannot be obtained by data comparison. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first purpose of the present invention is to propose a data comparis...
