Forward (model-first) and Reverse (schema-first) Mapping
You can start from the database or from your persistent classes. Telerik's .Net ORM can start from existing legacy databases, detect your data model, create object models, and even let you edit the object model. Alternatively, you can just start from your model of persistent classes and push those to the database. OpenAccess supports rich variety of mappings for collections and class hierarchies.

Build-time Bytecode Enhancement
No source code generation, easy to understand persistent classes, no mistakes can be made to break lazy loading or change tracking.

Testability
All classes enhanced by Telerik's .Net ORM are still normal CLR objects, and as such can be easily  tested by state of the art unit tests. Moreover, SQL code can be traced by writing it to the console, in a text file or to the .NET tracing framework. Performance counters show you the state of your running application, website or application server.
