Representing spatiality in a conceptual multidimensional model
Elzbieta Malinowski, Esteban Zimányi · 2004
Data Warehouses and On-Line Analytical Processing systems rely on a multidimensional model that includes dimensions, hierarchies, and measures. Such model allows to express users' requirements for supporting the decision-making process and to facilitate its afterward implementation. Although Data Warehouses typically include a spatial or location dimension, this dimension is usually represented in an alphanumeric format. However, it is well-known that a visual representation of spatial data allows to reveal patterns that are difficult to discover otherwise. Further, a multidimensional model is seldom used for representing spatial data.
