Exemples de vues analytiques et de requêtes SSB (Star Schema Benchmark)

Le schéma SSB contient les tables suivantes : lineorder, customer, supplier, part et dwdate. Vous trouverez ci-dessous une liste d'exemples de requêtes et de vues analytiques que vous pouvez utiliser pour le schéma SSB. Notez que vous devez préfixer les noms de table avec le nom de schéma SSB dans vos requêtes.

Remarque

SH et SSB sont fournis en tant qu'utilisateurs de type schéma uniquement. Vous ne pouvez donc pas déverrouiller ou supprimer ces utilisateurs ni définir un mot de passe. De plus, le stockage des ensembles de données échantillon ne compte pas dans le stockage de votre base de données.

Le tablespace de données échantillon contient uniquement les données échantillon et est en lecture seule et non crypté. Les données client ne peuvent pas être ajoutées à ce tablespace car celui-ci est en lecture seule et ne peut pas être modifié.

Vues d'analyse de référence de schéma en étoile

Vues analytiques SSB

Les vues analytiques permettent d'étendre facilement un schéma en étoile avec un modèle de gestion hiérarchique, des règles de calcul d'agrégation et de mesure, des métadonnées de présentation et des métadonnées propres à l'application qui peuvent être utilisées pour améliorer le contenu d'un ensemble de données et pour simplifier le développement d'applications décisionnelles. Le schéma SSB comprend une vue analytique et quatre hiérarchies qui utilisent les tables du schéma en étoile. Utilisez les requêtes suivantes pour interroger la vue d'exemple de SSB analytique. Notez que la vue analytique figure dans le schéma SSB.
