The data mart is defined as retail level of the DW. Different approaches and methods have been proposed to design it. In this paper, the authors propose an automatic way to generate the schema of the data mart from the OLAP requirements that are stored as schemas. Their solution consists on merging the schemas that belong to the same domain using schema integration method. This latter compares in the first step the elements of the schemas using matching technique, then it merges the global schema using the mapping technique.
