Abstract:
The present invention provides a way of managing databases when updating records in a local database where individual records in a source database are changed on a regular basis, but each record maintains a consistent unique record identifier. The first time a reviewer reviews a record resulting from a search, the reviewer accepts or rejects the record. If the record reappears in future additions to the database, e. g. , as a result of an update to the record, rejected records will be filtered before ever reaching the reviewer. Previously reviewed and accepted records can either be sent directly to a local database (again by-passing the reviewer) or forwarded to the reviewer if a significant field has been updated. In this manner the reviewer always sees brand new records, but avoids seeing updated versions of previously reviewed records unless some portion of the data has been updated which the reviewer considers significant. Local database users see only a single, fully updated version of each record.
