Towards Conceptual Multidimensional Design in Decision Support Systems
Olivier Teste
Multidimensional databases support efficiently on-line analytical processing (OLAP). In this paper, we depict a model dedicated to multidimensional databases. The approach we prese…
Elaboration d'entrepôts de données complexes
Olivier Teste
In this paper, we study the data warehouse modelling used in decision support systems. We provide an object-oriented data warehouse model allowing data warehouse description as a c…
Modélisation et manipulation de données historisées et archivées dans un entrepôt orienté objet
Franck Ravat, Olivier Teste
This paper deals with temporal and archive object-oriented data warehouse modelling and querying. In a first step, we define a data model describing warehouses as central repositor…
Contraintes pour modèle et langage multidimensionnels
Faiza Ghozzi, Franck Ravat, Olivier Teste +1
This paper defines a constraint-based model dedicated to multidimensional databases. The model we define represents data through a constellation of facts (subjects of analyse) asso…
Analyse multigraduelle OLAP
Gilles Hubert, Olivier Teste
Decisional systems are based on multidimensional databases improving OLAP analyses. The paper describes a new OLAP operator named "BLEND" to perform multigradual analyses. The oper…
Modélisation et extraction de données pour un entrepôt objet
Franck Ravat, Olivier Teste, Zurfluh Gilles
This paper describes an object-oriented model for designing complex and time-variant data warehouse data. The main contribution is the warehouse class concept, which extends the cl…
