13. At a computer system, the computer system including a processor and system memory, a computer implemented method for data mining on a multidimensional data cube, comprising: accessing multidimensional data; accessing multidimensional expressions defining how to view the multidimensional data as a multidimensional data cube; accessing data mining extensions for performing data mining on data residing in the multidimensional cube; integrating the multidimensional expressions and the data mining extensions into input for data mining model creation; the processor creating a data mining model trained on the multidimensional data from the input; storing the data mining model; performing data predictions against data contained in the multidimensional data cube by data mining the multidimensional data cube in accordance with the data mining model, data mining including performing data mining operations on portions of data contained in the multidimensional data cube in accordance with a multidimensional query element.
16. The method of claim 13 , wherein the data mining extensions correspond to MICROSOFT Data Mining Extension (DMX) specification.
