Modèle School

  • Article

Cette rubrique contient des informations sur le modèle conceptuel, le modèle de stockage et le mappage pour l'exemple de base de données School. Pour créer la base de données School, consultez Création de l'exemple de base de données School.

Le modèle School est utilisé dans l'exemple de code dans Entity Framework et dans la documentation Entity Data Model Tools. Les informations sur le modèle conceptuel, le modèle de stockage et le mappage sont exprimées dans les langages CSDL (Conceptual Schema Definition Language), SSDL (Store Schema Definition Language) et MSL (Mapping Specification Language), respectivement. La méthode recommandée pour créer le modèle de stockage, le modèle conceptuel et le mappage consiste à utiliser Entity Data Model Wizard ou l'outil en ligne de commande edmgen.exe.

Bb896300.note(fr-fr,VS.100).gifRemarque :
Pour plus d'informations sur l'utilisation de Entity Data Model Designer pour étendre le modèle School, consultez ADO.NET Entity Data Model Designer Scenarios.
