Problems solved by technology

It can be seen that this method is realized by querying a large amount of data, which will greatly affect the efficiency and accuracy of verification, cause the database migration cycle to be too long, and cause the business to suspend for a long time; more seriously, it often cannot target large data objects for fast and efficient validation
It is obvious that the limitations of traditional data verification methods have become a bottleneck in the development of cloud computing and big data technology.

Abstract

The invention discloses a database migration data verification method and system. The system comprises various source databases and target databases. The method comprises that a data segmentation module extracts data from the source databases and the corresponding target databases to form sample data blocks of data verification. A data block management module performs data attributive analysis on the sample data blocks to form sample data block basic information and compares the block basic information of the source databases with corresponding target database basic information to obtain the conclusion of the integrity of migration data. By means of the method and the system, the block basic information obtained through sample extraction by the source databases and the target databases is compared to verify the database migration data, and accordingly, the loads of former comparison of a large number of data are reduced greatly.

Description

technical field [0001] The invention relates to extraction, conversion and loading (ETL, Extraction-Transformation-Loading) technology of computer database data, in particular to a method and system for verifying database migration data. Background technique [0002] Data verification means that the data provider uses a specified algorithm to calculate a check value for the original data of the source database in order to ensure the integrity of the data, and the data receiver uses the same algorithm to calculate the check value for the migration data of the target database , if it is the same as the verification value calculated by the data provider on the original data, it means that the migrated data is complete. [0003] With the development of new technologies such as cloud computing and big data, the requirements for high efficiency and accuracy of data verification are getting higher and higher. Since the increase in the amount of data in applications far exceeds the...
