Data Warehouse Management
Selecting all data satisfying a condition along a particular dimension while navigating. A slice is a subset of a multidimensional array corresponding to a single value for one ore more members of the dimensions not in the subset. From an end user perspective, the term slice most often refers to a two-dimensional page selected form the cube.
