A multidimensional data process method and device thereof are disclosed in the present embodiments. The method comprises: obtaining attribute information in dimension information and hierarchical relationship information of respective attributes in a data service, and generating a recursive topology; and the recursive topology comprises an attribute composition set and recursive paths of respective attribute compositions in the attribute composition set; confirming attribute compositions for querying in the attribute composition set; confirming attribute compositions for fixing in the attribute composition set according to the attribute compositions for querying; fixing the attribute compositions for fixing to form fixed attribute compositions and obtaining index data in accordance with the fixed attribute compositions; recursing index data in accordance with the attribute compositions for querying. The present invention is applied to the multidimensional data analysis.
