This documentation article is a legacy resource describing the functionality of the deprecated OpenAccess Classic only. The contemporary documentation of Telerik OpenAccess ORM is available here.

Telerik OpenAccess ORM is a tool that supports development of data-oriented software applications. Telerik OpenAccess ORM tool is targeted at solving the object-relational impedance mismatch.

The object-relational impedance mismatch is a set of conceptual and technical difficulties which are often encountered when a relational database management system is being used by a program written in an object-oriented programming language. Relational and object-oriented models are so different that additional code and functionality is required to make them work together efficiently.

Using the Telerik OpenAccess ORM tool means that architects and developers of data-oriented applications will have the ability to concentrate on the logic of the business problems they are solving, instead of solving problems with the data engines used to store and retrieve the data.

Note that Terlerik OpenAccess ORM can be used in two modes:

The old mode, also called OpenAccess Classic, is a deprecated set of wizards and dialogs, including for instance the forward and reverse mapping wizards, and CRUD operations are accessed using the ObjectScope class and the object model around it. This documentation site is presenting only the old mode of usage.

The new mode uses tools like the OpenAccess Visual Designer, OpenAccess Domain Method Editor and many others for design-time mapping, while providing a new Context API based on OpenAccessContext class for executing CRUD operations. The documentation of the new mode is completely separated and fully describes the capabilities of the current OpenAccess ORM release.
