What is slice operation example?
The slice operation performs a selection on one dimension of the given cube, resulting in a subcube. Reduces the dimensionality of the cubes. For example, if we want to make a select where Medal = 5. Slice Operation. The dice operation defines a sub-cube by performing a selection on two or more dimensions.

What is OLAP slice?
A Slice represents two-dimensional view of an OLAP Cube that arranges data in a grid, similar to a spreadsheet; a Slice functions much like a report or a query in an RDBMS in that it returns data based on a request for what to see.
How many dimensions are selected in dice operation?
A : Only one dimension is selected for the slice operation. Q: How many dimensions are selected in dice operation? A : For dice operation two or more dimensions are selected for a given cube. Q: How many fact tables are there in a star schema?
What is Python slice?
Slicing in Python is a feature that enables accessing parts of sequences like strings, tuples, and lists. You can also use them to modify or delete the items of mutable sequences such as lists. Slices can also be applied on third-party objects like NumPy arrays, as well as Pandas series and data frames.
What are the types of OLAP?
