ABSTRACT:
A method for assembling data by sorting and filtering new data records and old data records, such as data records that an Electronic Program Guide data provider typically transmits to a head end of a cable television system. New incoming data records are combined with existing stored data records to form combined data records. Each of the data records is assigned an array index value. The combined data records are then sorted into one field of multiple fields. Within each field, each sorted data record is compared with other sorted data records and any conflicting data record is removed. The remaining non-conflicting data records are compared within each field and exact duplicate data records are removed from each corresponding field. The remaining processed data records are compared within each field and any older difference duplicate data record is removed. The filtered data records are then transmitted to a database. Because the filtered data records are purified and contain only current information, theoretically, the database will consume all data records. Reducing the number of data records transmitted to the database also reduces the time necessary to process the data records transmitted to the database.
