A highly-usable multidimensional data analysis method for performing interactive analysis on, for example, medical/administrative data stored in a hospital information system to support knowledge discovery about clinical decision-making is proposed. A multidimensional data analysis apparatus (200) includes: a database (201) separately holding an interval table I indicating intervals and a hierarchy table T indicating a hierarchical structure of each dimension of multidimensional data; an interval selection operation unit (202c) selecting an interval I′ having a user-requested property c from the interval table I, using an interval selection operation g; a join operation unit (202b) joining a set of intervals with a join operation (3 in the interval selected by the interval selection operation unit (202c), using the join operation β; and an aggregation operation unit (202a) generating a multidimensional cube from a result in the join operation unit (202b), using an aggregation operation α.
