              <p>Les vues matérialisées sont utilisées dans les systèmes de gestion de bases de données commercialisés pour accélérer le temps de traitement des requêtes. Cette technique est aussi très utile dans les entrepôts de données pour améliorer les performances des requêtes décisionnelles. Cependant, le problème de sélection de vues a été étudié surtout dans un contexte centralisé. Dans cet article, nous abordons le problème de sélection de vues dans un environnement distribué. Pour ce faire, nous avons étendu le concept des graphes de vues AND-OR qui permet de capturer les caractéristiques d'un système distribué. Nous proposons ensuite une méthode utilisant la programmation par contraintes pour la modélisation et la résolution du problème de sélection de vues sous des contraintes de ressources multiples. Nous montrons expérimentalement que notre approche fournit de meilleures performances au sens où elle permet d'améliorer la qualité des solutions en réduisant davantage encore le coût de traitement des requêtes.</p>
