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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for indexed-field based difference detection and correction","description":"A method and system for indexed field based difference detection and correction.
