Abstract

Un modèle de métadonnées définit des objets de modèle pour représenter une ou plusieurs sources de données. Le modèle de métadonnées comprend une couche d'accès aux données, une couche d'activités et une couche d'envoi. La couche d'accès aux données contient des objets de modèle d'accès aux données. Les objets de modèle d'accès aux données comprennent un objet de model d'accès aux données qui décrit comment extraire des données à partir des sources de données. La couche d'activités contient des objets de modèle d'activités. Les objets de modèle d'activités comprennent un objet de modèle d'activités qui décrit une vue opérationnelle de données dans les sources de données. La couche d'envoi contient des objets modèles d'envoi qui renvoient à des sous-catégories d'objets de modèle d'activités.
