  • Patent number: 10169303
    Abstract: A management system displays a plurality of elements detected from an information system according to a horizontal relation view (HRV) format which is a multi-column display format, based on information of the plurality of detected elements. In the HRV format display, the plurality of columns correspond to a plurality of types, and include a key column which is a column serving as a key for aggregated display and an aggregation target column subjected to aggregated display according to the key column. The key column includes key objects which represent information on elements belonging to the corresponding type and which are arranged vertically. A lateral area of each of the key objects in the aggregation target column includes aggregation objects indicating aggregation information of elements related to an element represented by the key object, whereby the key objects and the related aggregation objects are arranged on the same row.
