Query and data distribution strategy of data cube in cloud computation

Aiming at the features of data cube, the paper firstly defines the query equivalent set concept and other concepts. The query algorithm of data cube is proposed in the paper connected with the cloud computing environment. According to the influences of all aspects during the algorithm procedures, the data distributed strategy of data cube in the cloud computing environment is also proposed in the paper. The theoretical analysis and experimental results show that the data cube query and distributed strategy which is applied in the cloud computing environment proposed in the paper can effectively optimize data distribution and data query efficiency.
