Expert Solution & Answer
Chapter 13, Problem 19RQ
Explanation of Solution
Multidimensional Cube:
The multidimensional cube is an Online Analytical Processing (OLAP) cube used in the optimization of data warehouse and OLAP applications. In this, data is stored in the form of dimensions which helps in increasing the query time.
Slice technique related to multidimensional cube:
- It constructs a two-dimensional table or view by slicing the data cube.
- Drag and drop operation is used to produce the other types of views...
