A. Two dimensional cube
B. Multidimensional cube
C. N-dimensional cube
D. Cuboid
Answer:A

The generalization of cross-tab which is represented visually is ____________ which is also called as data cube.
A. Two dimensional cube B. Multidimensional cube C. N-dimensional cube D. Cuboid
Explanation:Each cell in the cube is identified for the values for the three dimensional attributes. 4. The process of viewing the cross-tab (Single dimensional) with a fixed value of one attribute is
