Abstract

The invention provides a data verification method and device. The method comprises the steps of obtaining a first data table of a first database and a second data table of a second database; respectively processing the first data table and the second data table to obtain a first feature matrix, a first MD5 feature value, a first data number, a second feature matrix, a second MD5 feature value anda second data number; verifying the first data number, the first feature matrix, the first MD5 feature value, the second data number, the second feature matrix and the second MD5 feature value; and ifthe verification is passed, determining that the data of the first database is consistent with the data of the second database. In the scheme, manual screening is not needed, and by verifying the number of the first data pieces, the first feature matrix and the first MD5 feature value of the first data table and the number of the second data pieces, the second feature matrix and the second MD5 feature value of the second data table, the data comparison time before and after migration can be shortened so as to ensure the consistency of the data before and after migration.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data verification method and device. Background technique [0002] With the continuous improvement of various enterprises' requirements for database performance, security and cost, in order to meet other requirements for database performance, security and cost, it is necessary to replace the database with better performance, security and cost. [0003] In the process of replacing the database, the data in the old database needs to be migrated to the new database. Since different databases store data in different ways, it is particularly important to ensure data consistency before and after migration during the database replacement process. At present, manual screening is often used to ensure the consistency of data before and after migration. It is necessary to manually compare the data in the old database before migration with the data in the new database after migrat...
