US Patent 7127475 Managing data integrity

Techniques are provided to manage the integrity of data stored in two or more data management systems by detecting inconsistencies between the data management systems. The techniques identify missing records in one or more data management systems by comparing the records in the data management systems. For records that exist in two or more data management systems, the techniques identify records that are not identical in the data management systems. A user checkpoint is provided between the identification of missing records and the identification of records that are not identical. The detected inconsistencies also may be corrected.
