Today companies need strategic information to counter fiercer competition, extend market share and improve profitability. So they need information system that is subject oriented, integrated, non volatile and time variant. Data warehouse is the viable solution. It is integrated repository of data gathered from many sources and used by the entire enterprise. In order to standardize data analysis and enable simplified usage patterns, data warehouses are normally organized as problem driven, small units called data marts. Each data mart is dedicated to the study of a specific problem. The data marts are merged to create data warehouse.
