摘要
PROBLEM TO BE SOLVED: To provide a data aggregation device, a data aggregation method and a data aggregation program capable of efficiently aggregating numerical values with respect to an object even for plural objects having hierarchical structures.SOLUTION: A data aggregation device: (1) acquires lowest layer identification data associated with input hierarchical structure identification data by referring to object management data including hierarchical structure identification data to identify a hierarchical structure with objects organized in lowest and higher layers and the lowest layer identification data to identify an object in the lowest layer; (2) extracts numerical values associated with the acquired lowest layer identification data by referring to aggregation object data including the lowest layer identification data and the numerical values; and (3) aggregates the extracted numerical values.SELECTED DRAWING: Figure 14
