1. A computer-implemented method for presenting a view of data in a multidimensional database the method comprising: assigning aggregate measures of orthogonality to one or more combinations of two or more columns in the multidimensional database; wherein each aggregate measure of orthogonality indicates a measure of interdependence between values in a first column and values in one or more other columns; determining a view of data based at least upon said aggregate measures of orthogonality, said determining including determining an orthogonal basis for the view; wherein said view is of a subset of data in the multidimensional database; wherein said orthogonal basis is one or more columns of the multidimensional database selected based on the aggregate measures of orthogonality; and displaying said view of data.
