Embodiment 1

[0048] This embodiment provides a data comparison method, such as figure 1 shown, including:

[0049] Step 101, determining the first data set and the second data set to be compared, and each comparison object in the first data set and the second data set includes one or more comparison items;

[0050]Step 102, determining the type of the comparison item, the type at least including: first-type comparison items and non-first-type comparison items;

[0051] Step 103, compare the comparison object in the first data set with the comparison object in the second data set, wherein, if the first comparison item of the first comparison object in the first data set is the same as the second The corresponding first-type comparison items in the second comparison object in the data set are the same, and the difference between the non-first-type comparison items of the first comparison object and the corresponding non-first-type comparison items of the second comparison object If the pre...

Embodiment 2

[0095] This embodiment provides a data comparison device, such as figure 2 shown, including:

[0096] The data set configuration module 201 is configured to determine the first data set and the second data set to be compared, and each comparison object in the first data set and the second data set includes one or more comparison items; and, Determine the type of the comparison item, the type at least includes: a comparison item of the first type and a comparison item of a non-first type;

[0097] A comparing module 202, configured to compare the comparison object in the first data set with the comparison object in the second data set, wherein, if the first comparison item of the first comparison object in the first data set and The corresponding first-type comparison items in the second comparison object in the second data set are the same, and the non-first-type comparison items of the first comparison object are the same as the corresponding non-first-type comparison items...

Abstract

The invention provides a data comparing method. The method comprises the steps of determining a first dataset and a second dataset to be compared, wherein each comparative object in the datasets comprises one or a plurality of comparative items; determining the type of the comparative items, wherein each type at least comprise a first class comparative item and a non first class comparative item; comparing a comparative object in the first dataset with a comparative object in a second dataset, if the first class comparative item of the first comparative object in the first data set is identical to a corresponding first class comparative item in a second comparative object in the second dataset, and a difference between the non first class comparative item of the first comparative object and a corresponding non first comparative item of the second comparative object, judging the first comparative object to be consistent with the second comparative object. The invention further provides a data comparing device. The efficient data comparison can be realized.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a data comparison method and device. Background technique [0002] In the common cross-platform data migration scenario, when the computing kernel and data storage format of the two platforms change, it is usually necessary to compare the data before and after the migration. If the amount of data is relatively small, manual verification can be performed, or some common DIFF (difference comparison) tools can be used, such as the diff command in the LINUX system. If the amount of data to be compared is massive, for example, when there are hundreds of millions of data records to be compared, it is impossible to complete it only by manual verification or conventional tools. [0003] The shortcoming of prior art mainly concentrates on the following aspects: [0004] 1) The efficiency of ordinary tools is low, and the cost of time resources is uncontrollable; [0005] 2) Bas...
