<P>PROBLEM TO BE SOLVED: To sort data contents without overlapping between multiple databases. <P>SOLUTION: A database management device provided in the present invention transmits a processing content received from a processing content input device to any one of multiple database devices. The database device obtains correspondence relation information associating a data block identifier referred to by the processing content with a database identifier from memory management means, and transmits the information to the database management device. The database management device stores the correspondence relation information in reference destination data block memorizing means. When a processing request is input, the database management device obtains the data block identifier corresponding to the processing and the database identifier from the reference destination data block memorizing means, and determines whether or not the data block identifier is made responsive to any of the database identifiers. When it determines that the data block identifier is not made responsive, the database management device stores the data block identifier upon making it responsive to the database identifier having the fewest total number of data blocks which have already been made responsive in the correspondence relation memorizing means, and sorts processing input by the process input device into a database having the most data block identifiers which are made responsive. <P>COPYRIGHT: (C)2012,JPO&INPIT |
