Résumé :

In the context of CASE tool development for relational database design, this paper develops a methodology that maps an enhanced Entity- Relationship (ER) schema into a relational schema and normalizes the latter into inclusion normal form (IN-NF). Unlike classical normalization that characterizes individual relations only, IN-NF concerns interrelational redundancies. The paper formalizes sources such redundancies in ER schemas. Our methodology enhances several other proposals, in particular [10]. The paper briefly presents our implementation of the methodology using Prolog.
