About the Book

Ce livre vise trois objectifs, relevant de l'ingénierie des données:

  • Savoir réaliser un modèle logique de données relationnel qui servira de référence pour implanter une base de données et concevoir aisément les requêtes SQL.
  • Savoir passer d'un modèle conceptuel de données, relevant de l'analyse métier, à un modèle logique de données relationnel relevant de l'informatique. (Voir le livre: Modèle conceptuel de données de P.-A. Sunier)
  • Connaitre les principes de transformation d'un modèle conceptuel de données basé en un modèle logique basé sur des contraintes déclaratives en lieu et place des contraintes structurelles usuelles. Les contraintes déclaratives permettent d'implanter des schémas de bases de données relationnelles offrant la souplesse nécessaire à l'agilité attendue d'un système d'information contemporain.
Dans une démarche progressive d'apprentissage, le livre vous présente:
  • Les règles d'élaboration de modèles logiques de données relationnels.
  • Le mécanisme de normalisation permettant de s'assurer de la relationnalité (bienfacture) des modèles élaborés.
  • Les règles d'obtention d'un modèle logique de données relationnel à partir de la transformation d'un modèle conceptuel de données.
Le livre est formé de six parties:
  • Introduction aux systèmes d'information informatisés d'entreprise.
  • Bases du modèle relationnel.
  • Modèle logique de données relationnel (MLD-R).
  • Normalisation et formes normales.
  • Transformation d'un MCD en utilisant les contraintes structurelles du MLD-R.
  • Transformation d'un MCD en utilisant les contraintes déclaratives du MLD-R.

De caractère pédagogique, le livre s'adresse aux étudiants et enseignants du domaine de l'informatique qui doivent assurer le lien entre l'analyse métier ou des affaires et l'architecture des bases de données relationnelles. Le professionnel pourra confronter sa pratique aux diverses propositions tendant à transformer des modèles conceptuels de données en modèles logiques de données relationnels sans contraintes structurelles dans le but de privilégier l'agilité du schéma relationnel.
About the Author: Pierre-André Sunier a été professeur d'informatique de gestion à la Haute école Arc de Neuchâtel (Suisse). Il a enseigné la méthodologie, la modélisation et le génie logiciel; il a mené plusieurs projets de recherche traitant de l'ingénierie, du développement de logiciels de gestion ou de l'évolutivité des systèmes d'information informatisés et a participé à de nombreux projets d'informatisation d'organismes privés ou publics.
