<p>PROBLEM TO BE SOLVED: To support the determination of an item to be used for the viewpoint of analysis, and to provide a device capable of providing data to be handled from this viewpoint by recomposing the contents of a database of the viewpoint composed of the combination of the time of a prescribed unit, the identification information of a table and an item value possible for the item of the table to take. SOLUTION: A data generator 4 inputs two-dimensional (2D) table format data stored in a database 1, time conditions 2 and item value conditions 3. Then, the 2D table format data are constituted again from three viewpoints of 'names of all tables M1-M4 and T1-T3 provided in data base 1', 'time' and 'combination of item values adoptable for arbitrary items in tables M1-M4 and T1-T4' and a multilayer nest table 5 is generated. The data generator 4 finds a reconstituted data structure with a condition processing part 6, a combination generating part 7 and a multilayer nest table generating part 8 or the like. Then, data for providing the reconstituted data structure are stored by an extracting part 9 and a storage part 10.</p> |
