Zusammenfassung:	A plurality of databases can be coupled after aligning time stamp cycles of data of the databases. An item (LEVEL) for designating a time stamp accuracy is added to an inquiry syntax (SQL syntax) of a query. At the time of table coupling, a query designating the desired accuracy in LEVEL is transmitted. This query is analyzed by a query purser 101b, and individual queries are created for each database targeted for inquiry and transmitted. At the time of coupling acquired tables, the number of digits of the time stamps is adjusted to be the same in accordance with the designated accuracy, and the tables are coupled in chronological order of the time stamps.
