A data join system of the present invention includes a table determination unit 11 selecting a record b as a join target if a value of a key item included in a record a acquired by a data write unit from a table A falls within a first predetermined range set based on a value of a key item included in the record b stored in a table B, a data join unit joining the selected record b with the record a to generate a record c, and a data write unit storing the record c into a table C. Thus, the success rate of data join can be improved while the accuracy of join of the record b and the record a to be joined is improved.

A copyright information management system supporting the management and protection of products comprised of digitalized multimedia content in a product distribution environment. The copyright information management system (10) provides a copyright information management center (11), provided in a product distribution environment (15) where products are distributed through communications lines (14) between a product provider (12) including at least one of a copyright owner and distributor and a product user (13) receiving the product, for exchanging information relating to the products through the communications lines (14). The copyright information management center (11) centrally manages all copyright information through the communications lines (14) by preregistering copyright information relating to the individual products in the center (11).
摘要:
To estimate the number of mobile terminals that have been staying in an observation area for a desired period of time, the feature quantity calculation portion 17 calculates a feature quantity for observation target location data based on location acquisition time information contained in the observation target location data acquired by the observation target acquisition portion 15. The expected stay time calculation portion 18 calculates an expected stay time in an observation area to be observed and, based on the expected stay time, the passing/staying terminal selection portion 19 selects mobile terminals to serve as a target of terminal quantity estimation. Then, the terminal quantity estimation portion 20 estimates the number of mobile terminals calculated as the target of estimation. In this manner, the terminal quantity estimation device 10 estimates the number of mobile terminals that have been staying in the observation area for a desired period of time.
