Abstract
Our approach seeks to reduce the complexity of this type of calculation through approximation and pre-computation. It is designed to work efficiently with modern relational database constructs for content management. The approach is designed to enable the kinds of highly interactive data-driven visualizations that are the hallmark of third generation business intelligence.
