Most applications are currently written on top of relational databases. At some point, these applications will have to interact with the data represented in a relational form. Database schemas are not always ideal for building applications, and the conceptual models of applications differ from the logical models of databases. The OpenAccess Domain Model is a conceptual domain model that can be used to model the data of a particular domain so that applications can interact with data as objects.

Therefore Telerik OpenAccess ORM includes LINQ to OpenAccessContext support. It enables developers to write queries against the database from the same language used to build the business logic.
The following topics show how to query a domain model by using Language-Integrated Queries (LINQ):
