Defining Identity Mechanisms - Overview
This article is relevant to entity models that utilize the deprecated Visual Studio integration of Telerik Data Access. The current documentation of the Data Access framework is available here.

The identifier has to be defined when the object is made persistent (except when a key generator mechanism is used). Using this identifier, you can directly retrieve an object from the database.
The topics in this section demonstrate how to work with the different Identity Mechanisms:
