WebWhat is Sparsity? When there are a large number of empty cells in a cube, the cube is said to be “sparse.” This is very common in dimensional data models. Most commonly, all dimensions are marked as sparse. When one or more dimensions as marked as sparse, OLAP creates a special index for the cube that automatically manages sparsity.

WebIn the field of numerical analysis, a sparse matrix is a matrix populated primarily with zeros as elements of the table. By contrast, if the number of non-zero elements in a matrix is relatively large, then it is commonly considered a dense matrix. The fraction of zero elements (non-zero elements) in a matrix is called the sparsity (density).
