Combining multidimensional expressions and data mining extensions to mine OLAP cubes

A language schema that integrates multidimensional extensions (e.g., MDX) and data mining extensions (e.g., DMX) for performing data mining operations on data residing in OLAP cubes. The schema provides that the can not only be a relational query, rather a multidimensional query formed using MDX, for example. The operations of model creation, training and prediction are described.
