Decision Support System (DSS) designers face two data models complexities: OLTP (On Line Transaction Processing) database model and multidimensional model. These models relying on different concepts force the designer to have double skills. The objective of this paper is to assist the DSS designer producing rapidly Data Mart (DM) schemas starting from the Data Warehouse (DW) data model. More accurately, we aim to automate the generation of DM schemas from a relational DW schema according to the MDA (Model Driven Architecture) paradigm. To do so, we propose an approach based on a set of transformation rules that we define in ATL language and illustrate with an example.
