  • Data validation for data record migrations
    Patent number: 11526470
    Abstract: Methods, systems, and devices for data validation are described. A user may store a set of data records on a source database and backup the set of data records at a target database through a data migration. A migration and validation server may initiate the data migration. After the data migration is complete, the migration and validation server may perform a validation process that includes comparing a calculated hash value from the source database and the target database that is based on unique identifiers and timestamps for each data record in the set of data records migrated from the source database to the target database. The migration and validation server may determine if the data migration was successful (e.g., the data was transferred correctly) if the hash value calculated for the data records at the target database equals the hash value calculated for the data records at the source database.
