In data manipulation contexts, a data cube is a multi-dimensional array of values. A data cube can be visualized as the multidimensional extension of two-dimensional table. It can be viewed as a collection of identical 2-D tables stacked upon one another. Data cubes are used to represent data that is too complex to be described by a traditional table of columns and rows. Typically, the data cube is applied in conditions where these arrays are massively larger than the hosting computer’s main memory, for example multi-terabyte data warehouses o time series of image data.
