A flexible approach to the multidimensional model: The fuzzy datacube

By Miguel Delgado, Carlos Molina, Daniel Sánchez, Lázaro Rodriguez Ariza and M. Amparo Vila


Abstract. As a result of the use of OLAP technology in new fields of knowledge and the merge of data from different sources, it has become necessary for models to support this technology. In this paper, we propose a new multidimensional model that can manage imprecision both in dimensions and facts. Consequently, the multidimensional structure is able to model data imprecision resulting from the integration of data from different sources or even information from experts, which it does by means of fuzzy logic.
