MULTI-DIMENSIONAL DATA ANALYZING METHOD, MULTI-DIMENSIONAL DATA ANALYZING DEVICE, AND PROGRAM

摘要

A multi-dimensional data analyzing method having high usability for interactively analyzing, e.g., medical data and management data stored in a hospital information system so as to assist discovery of knowledge about clinical decision. A multi-dimensional data analyzing device (200) comprises a database (201) holding separately a section table (I) showing sections and a hierarchy table (T) showing the hierarchical structure of the dimensions of multi-dimensional data, a section selection operation block (202c) for selecting a section (I') having a property (c) requested by a user from the section table (I) by using a section selection operation g, a join selection operation block (202b) for joining a set of sections with a join selection operation ß by using a join selection operation ß in the selected section (I'), and aggregation operation block (202a) for creating a multi-dimensional cube from the result obtained by the join selection operation block (202b) by using an aggregation operation a.
