Esquema conceptual de AdventureWorks Sales (EDM)

.NET Framework 3.5

El modelo de AdventureWorks Sales es una implementación de Entity Data Model (EDM) basada en las tablas del ejemplo AdventureWorks que se distribuye con SQL Server. Se declaran cinco entidades:

  • Address

  • Contact

  • Product

  • SalesOrderDetail

  • SalesOrderHeader

Los conjuntos de entidades del mismo nombre del modelo de objetos generado a partir del esquema conceptual contienen lógicamente instancias de estos tipos.

Se declaran tres asociaciones y conjuntos de asociaciones. Los nombres de las asociaciones siguientes comienzan con FK_. Esto refleja las relaciones de clave externa en las tablas de datos de Aventure Works.

FK_SalesOrderDetail_SalesOrderHeader_SalesOrderID

FK_SalesOrderHeader_Address_ShipToAddressID

FK_SalesOrderHeader_Contact_ContactID

Esquema CSDL

Las entidades y asociaciones de este modelo se declaran y definen en el lenguaje de definición de esquemas conceptuales (CSDL). El esquema completo se muestra en el ejemplo siguiente.
