| Abstract: | Researching on the multi - dimensional queries technology is likely to be of considerable practical importance due to recent developments of modern industry and enterprise. A good multi - dimensional query technology can be used to explore the information in the data warehouse with high performance,high guality and high efficiency. In this paper, three optimal plans for optimizing multiple dimensionalqueries are presented on the basis of the shared - scan idea and an analysis and comparison are made ofthe three algorithms for the three optimal plans. |
