We can represent three dimensions in our data warehouse as a cube. Which of the following is the operation that will enable viewing a small sub-cube taken from the original as shown below? Large cube on the left made of 27 smaller cubes. One of those smaller cubes is separated to the right. Group of answer choices pivot dice slice roll-up drill-down

05. Assume a base cuboid of 10 dimensions contains only three base cells: (1) (a1, d2, d3, d4, ..., d9, d10), (2) (d1, b2, d3, d4, ..., d9, d10), and (3) (d1, d2, c3, d4, ..., d9, d10), where a1 ≠d1, b2 ≠d2, and c3 ≠d3. The measure of the cube is count. (a) How many nonempty cuboids will a full data cube contain? (b) How many nonempty aggregate (i.e., nonbase) cells will a full cube contain? (c) How many nonempty aggregate cells will an iceberg cube contain if the condition of the iceberg cube is "count ≥ 2"? (d) A cell, c, is a closed cell if there exists no cell, d, such that d is a specialization of cell c (i.e., d is obtained by replacing a * in c by a non-* value) and d has the same measure value as c. A closed cube is a data cube consisting of only closed cells. How many closed cells are in the full cube?

Which of the following is true? The base cuboid has one single row of data. The apex cuboid aggregates data on all dimensions of the data cube. The apex cuboid has the largest number of rows in the cube. The apex cuboid has more rows than the base cuboid.
Which of the following statements is false? A cube has the same number of cuboids as the number of dimensions in the base cuboid. A data cube aggregates fact data along all subsets of its dimensions. A cuboid is a section of a cube along a subset of its dimensions. A data cube is built around dimensions and facts.
