7. Why Using ORM? Facilitates implementing the Domain Model pattern. Huge reduction in code. Changes to the object model are made in one place. Rich query capability. Navigation. Data loads are completely configurable. Concurrency support. Cache management. Transaction management and Isolation. Key Management. 7

9. What is Telerik OpenAccess? Telerik OpenAccess is an Enterprise-grade .Net ORM that does the data access plumbing in desktop and web applications. Supporting both forward (model-first) and reverse (schema-first) mapping, The tool offers transparent persistence for your DAL and business objects. OpenAccess ORM provides tight Visual Studio integration and allows you to seamlessly create database independent code. 9

28. Disconnected API OpenAccess unique ObjectContainer API concept has been the first ORM feature supporting disconnected data scenarios. The offline ObjectContainer API shares a common interface with the online ObjectScopeAPI The ObjectContainer serves as a bag which can hold object network, provides serialization, change tracking and the ability to apply changes in a round-trip fashion to the database. 28

30. Partial Trust Most O/R products do not support the partial trust paradigm out of the box. Most commonly the support was tied to severe limitations of the products functionality. Most popular products like Linq To Sql and Entity Framework had issues on their own with the partial trust support. 30
