"fr" => "Les entrepôts de données reposent essentiellement sur la modélisation multidimensionnelle. A l'aide d'outils OLAP, les décideurs analysent les données à différents niveaux d'agrégation. Il est donc nécessaire de représenter les connaissances d'agrégation dans les modèles conceptuels multidimensionnels, puis de les traduire dans les modèles logiques et physiques. Cependant, les modèles conceptuels multidimensionnels actuels représentent imparfaitement les connaissances d'agrégation. Afin de prendre en compte les caractéristiques de ces connaissances, nous proposons de les représenter avec des objets (diagrammes de classes UML) et des règles en langage PRR (Production Rule Representation). Nous présentons notre approche et l'illustrons au moyen d'un scénario d'application. Les entrepôts de données reposent essentiellement sur la modélisation multidimensionnelle. A l'aide "
"en" => "Data warehouses are mainly based on multidimensional modeling. Using OLAP tools, decision makers analyze data at different aggregation levels. Therefore, aggregation knowledge should be adequately represented in conceptual multidimensional models, and mapped in subsequent logical and physical models. However, current conceptual multidimensional models poorly represent aggregation knowledge. In order to account for the characteristics of this knowledge, we propose to represent it with objects (UML class diagrams) and rules in Production Rule Representation (PRR) language. We present our approach and illustrate it with an application scenario. Data warehouses are mainly based on multidimensional modeling. Using OLAP tools, decision makers ana "
