ABSTRACT:
A method and system for indexed field based difference detection and correction. A data feed file is partitioned into a plurality of subsets based on an indexed field of the data feed file. A redundancy check value is calculated for each of the subsets, and the redundancy check value is compared to a database file which corresponds to each subset. If the redundancy check values do not match for a subset and a corresponding database file, a difference is detected between the subset and the corresponding database file and the corresponding database file is replaced by the subset.
