Abstract

The decision-making process can be supported by many tools such as Data Warehouse (DW), On-Line Analytical Processing (OLAP) and Geographical Information System (GIS). Much research found in database literature is aimed at integrating these technologies. However, most of them do not specify neither evaluate multidimensional-geographical processing algorithms. This paper proposes two algorithms, named MDFirst and GEOFirst, and presents some results derived from an statistical analysis that was carried out to determine which of them gets the best performance evaluation results. These results showed that the GEOFirst algorithm is more suitable when compared to the other one.
