School Model
This topic contains the conceptual model, storage model, and mapping information for the School sample database. To create the School database, see Creating the School Sample Database.
The School model is used in example code in the Entity Framework and Entity Data Model Tools documentation. The conceptual model, storage model, and mapping information are expressed in conceptual schema definition language (CSDL), store schema definition language (SSDL), and mapping specification language (MSL), respectively. The recommended way to create the storage model, conceptual model, and mappings is by using the Entity Data Model Wizard or the edmgen.exe command line tool.
Note
For information about using the Entity Data Model Designer to extend the School model, see ADO.NET Entity Data Model Designer Scenarios.
Model and Mapping Definitions
The following code contains the conceptual content, storage content, and mapping content for the School model.
