AdventureWorks Sales Conceptual Schema (EDM)

  • Article

The AdventureWorks Sales Model is an Entity Data Model (EDM) implementation based on the tables in the AdventureWorks sample that ships with SQL Server. Five entities are declared:

  • Address

  • Contact

  • Product

  • SalesOrderDetail

  • SalesOrderHeader

Instances of these types are logically contained by entity sets of the same name in the object model built from the conceptual schema.

Three associations and association sets are declared. The names of the following associations all begin with FK_. This reflects foreign key relationships in the tables of the Adventure Works data.

FK_SalesOrderDetail_SalesOrderHeader_SalesOrderID

FK_SalesOrderHeader_Address_ShipToAddressID

FK_SalesOrderHeader_Contact_ContactID

CSDL Schema

The entities and associations of this model are declared and defined in conceptual schema definition language (CSDL). The complete schema is shown in the following example.
