Multivariate and multidimensional OLAP

1998
The author presents a new relational approach to multivariate and multidimensional OLAP. In this approach, a multivariate aggregate view (MAV) is defined. MAV contains categorized univariate and multivariate aggregated data, which can be used to support many more advanced statistical methods not currently supported by any OLAP models.
