The present invention processes a database by sorting the database based on an address. One device according to the present invention includes a classifying unit which classifies entries of the database into entries which are divided into a plurality of sub-databases according to a classification level designated as an address element, and an organizer which adds the entries obtained from the database to the corresponding sub-database with a sorting method as an order to designate the entries of the corresponding sub-database for each sub-database based on the address information of the entry. Each sub-database is composed of the entries with the same information for the designated address element by the classification. The entries with different information for the designated address element are between the sub-databases. |
