What is a 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.  In an Cube, a Slice can, optimally, be created through drag-and-drop of Dimensions and their Members; optimally, the Slice view will refresh instantaneously.
