      "fr" => "L'article aborde le problème de l'intégration de contraintes en conception de base de données. L'approche s'insère dans la méthodologie de conception incrémentale de base de données inhérente au système KHEOPS. L'étape d'intégration de vues par unification sémantique est suivie par la confrontation des contraintes d'intégrité initiales. La phase de détection est un processus déductif dans lequel les contradictions et redondances entre les contraintes sont exhibées. La résolution des conflits dépend ensuite de la stratégie choisie par le concepteur. Quatre stratégies sont proposées et discutées. Un exemple d'utilisation est donné pour chacune. Cette approche pourrait être étendue au contexte orienté objet où à la fois  contraintes et méthodes sont à comparer."
      "en" => "This paper addresses the problem of constraint integration in database design. The approach is inserted in an incremental database design methodology supported by the design environment KHEOPS. This view integration step using semantic unification is followed by the initial constraint confrontation. The detection phase is a deductive process in which the contradictions and redundancies between constraints are exhibited. The following conflict resolution depends on the strategy initially chosen by the designer. Four strategies are presented and discussed. An exemple of use is given to illustrate the application of those strategies. This approach could be enlarged in an object oriented context where schemata would have not only constraints but also methods to compare."
