Logical Data Marts

Perhaps the ideal approach to incorporating the data mart concept into your data warehouse is to construct one or more logical, or virtual, data marts. By using a system of carefully constructed views on the detail data of the warehouse, you can design multiple user- or department-specific virtual data marts that provide the same sort of highly tailored information a physical data mart would without the need for massive data loads, cleansing, and other necessary transformations.
