Un Profil UML pour les Entrepôts de Données Intégrant les Réseaux Spatiaux
Résumé
Spatial Data Warehouses (SDW) and Spatial OLAP (SOLAP) systems allow the storage and multidimensional analysis of huge volumes of geographic data. Existing SOLAP models do not take into account connectivity of spatial objects and consequently they do not natively integrate networks. In this paper, we propose a UML (Unified Modeling Language) profile for SDW integrating spatial networks. We implemented our UML profile using UML meta-model elements and OCL (Object Constraint Language) constraints with a Computer-Aided Software Engineering tool (MagicDraw). The implementation of the conceptual model in a database is presented using Oracle.
