Abstract
Records stored in a database are reset on an as-accessed basis. A record in the database to receive new data is identified when new data arrives to be incorporated with existing data in a given field. A next reset date stored in the record is read and compared with the current date. If the current date is later than the next reset date, the existing data in the field is replaced with a predetermined default value prior to incorporating or incrementing the new data in the field. Additionally, another next reset date is calculated and substituted for the previous next reset date in the record.
