Abstract:
In this work, we do an analysis on the different models proposed to model Multidimensional Databases MDB, and Spatial Databases SD. We analyze the basic and advanced rules that the conceptual multidimensional models should to support, according sort criterion exposed for some authors. As result of this study, we propose to add new rules to gather the spatial and temporal semantics. Are analyzed some of models more relevant, and a comparative table is presented, where the advantages of the model called FactEntity FE, with respect to the other examined modes, to collect multidimensional and spatial semantics, is obvious. We emphasizing on the novel contributions of FE model and shortcomings of the rest of seen models. We besides show a formalization of the FE model with a metamodel made up with the extended ER model, where the semantics of FE model is representing. Finally, an example of application clarifies our exposure.
