In the Crunch system, any analysis is also referred to as a “cube”. Cubes are the mechanical means of representing analyses to and from the Crunch system; you can think of them as spreadsheets that might have other than two dimensions. A cube consists of two primary parts: “dimensions” which supply the cube axes, and “measures” which populate the cells. Although both the request and response include dimensions and measures, it is important to distinguish between them. The request supplies expressions for each, while the response has data (and metadata) for each. The request declares what variables to use and what to do with them, while the response includes and describes the results. See Object Reference:Cube for complete details.
