<p><P>PROBLEM TO BE SOLVED: To provide a period division statistical program minimizing a load of a computer necessary for recalculation. <P>SOLUTION: A statistic system 111 stores a statistical target information 123 in a storage device 12 when the statistical target information 123 is inputted. When respective unit periods defined by a statistic calculation rule 124 are terminated, the statistic system 111 reads all the statistical target information for the unit periods including an event occurrence time point from the storage device 12, executes statistical calculation, and registers the statistical result in statistical information 122 inside the storage device 12. When statistical target information is inputted, the statistic system 111 reads all the statistical target information for the unit periods including the event occurrence time point as to the unit periods including the event occurrence time shown by the statistical target information about the respective unit periods for which statistical results are stored in the statistical information 122, executes statistical calculation again, and overwrites the statistical result to the statistical information 122 inside the storage device 12. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
