<p>An advanced credit reporting and query system receives credit information into a central database (4) to service queries and provide other output. Unlike conventional credit reporting systems, the database is encoded to identify those fields which have changed since the last update (20) to the database, so that rewriting of the same data on the same fields is avoided. Database coherency and detection may be performed by hashing (24) or other techniques.</p> |
