Schéma de stockage de l'exemple de base de données AdventureWorks Sales (EDM)

Dans le modèle EDM (Modèle de données d'entité), les métadonnées de stockage sont définies dans le langage SSDL (Store Schema Definition Language). Dans cet exemple, le schéma SSDL représente les tables et les clés des données de l'exemple de base de données Adventure Works.

Schéma SSDL

L'exemple suivant contient les métadonnées de cinq tables de la base de données Adventure Works. La syntaxe XML est utilisée pour définir les structures du modèle de stockage. Les jeux d'entités représentent les tables. Les types d'entités représentent les lignes. Les propriétés représentent les colonnes des lignes. Les associations représentent les relations de clé étrangère. Les ensembles d'associations définissent de manière logique la portée des associations.

Ce schéma est utilisé pour mapper au stockage le modèle utilisé dans la rubrique précédente Schéma conceptuel des ventes AdventureWorks (EDM).

Le schéma SSDL complet est présenté dans l'exemple ci-dessous.
