Data cube
（重定向自Datacube）
In computer programming contexts, a data cube (or datacube) is a three- (or higher) dimensional array of values, commonly used to describe a time series of image data. A data cube is also used in the field of imaging spectroscopy, since a spectrally-resolved image is represented as a three-dimensional volume. The data cube is used to represent data along some measure of interest. Even though it is called a 'cube', it can be 2-dimensional, 3-dimensional, or higher-dimensional. Every dimension represents a new attribute in the database and the cells in the cube represent the measure of interest.
