An OLAP cube is a multi-dimensional array of data.^[1] Online analytical processing (OLAP)^[2] is a computer-based technique of analyzing data to look for insights. The term cube here refers to a multi-dimensional dataset, which is also sometimes called a hypercube if the number of dimensions is greater than three.
