Wikipedia on Array is very broad ranging: http://en.wikipedia.org/wiki/Array
Wikipedia on Array Data Structure: http://en.wikipedia.org/wiki/Array_data_structure contains a sentence about "three-dimensional", in the section on "Meaning of Dimension": "a three-dimensional array a block of data". However, the rest of the paragraph doesn't seem quite right. The Database and Data Warehouse usage of "cube" is referenced here: http://en.wikipedia.org/wiki/OLAP_cube OLAP cubes can be thought of as extensions to the two-dimensional array of a spreadsheet. For example a company might wish to analyze some financial data by product, by time-period, by city, by type of revenue and cost, and by comparing actual data with a budget. These additional methods of analyzing the data are known as dimensions.[3] Because there can be more than three dimensions in an OLAP system the term hypercube is sometimes used. Wikipedia on Hypercube: http://en.wikipedia.org/wiki/Hypercube >From Wikipedia: http://en.wikipedia.org/wiki/Tesseract A generalization of the cube to dimensions greater than three is called a "hypercube", "n-cube" or "measure polytope". The tesseract is the four-dimensional hypercube, or 4-cube. Alan On Oct 23, 2011, at 7:10 PM, Henry Rich wrote: > 'cube' was suggested.
