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.

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 ObjectScope API

• 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.

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.
