2014 Lecture Notes in Computer Science  
Then, in this paper we present a new prototyping methodology for DWs, extending [3] , where DM methods are used to define the DW schema.  ...  Some work about the integration of Data Mining and OLAP systems has been done to enhance OLAP operators with mined indicators, and/or to define the DW schema.  ...  Our tool uses a clustering algorithm to create automatically a hierarchy in a dimension of the prototype of OLAP cube.  ...
