Traditionally, OLAP operations are more focused on retrieving data from a single data mart. An exception is the drill across operator. This, however, is restricted to retrieving facts on common dimensions of the multiple data marts. Our concern is to define further operations while retrieving data from multiple data marts. Towards this, we have defined six operations which coalesce data marts. While doing so we consider the common as well as the non-common dimensions of the data marts.}, journal = {International Journal of Computer and Information Engineering}, volume = {2}, number = {11}, year = {2008}, pages = {3931 - 3936}, ee = {https://publications.waset.org/pdf/15559}, url = {https://publications.waset.org/vol/23}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 23, 2008}, }
