In this sense, we can define the various ''ways'' of data to analyze:

* ''One-way data array'' with ''N'' entried (dimensions) stores an ''N''-dimensional [[Vector (mathematics and physics)|vector]].

* ''Two-way data array'' stores a grid of data, a "data [[matrix (mathematics)|matrix]]";. aA [[spreadsheet]] can be used to visualize such data in the case of discrete dimensions.

* ''Three-way data array'' stores a cube of data. Such data might represent the temperature at different locations (two-way data) sampled over different times (leading to three-way data)

* ''Four-way data array'', using the same spreadsheet analogy, can be represented as a file folder full of separate workbooks.
