Glossary Item Box

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 enables the developer to use two approaches in producing an application datamodel: Forward-Mapping and Reverse-Mapping.

 

Forward Mapping

Forward-Mapping contains of defining a Class-Model in an object-oriented environment(C# or VB. NET) and then map the class model to a relational datbaase-model. Every class maps to a table, references to other class generate constraints, collections fields map to join-tables or m:n relations between tables depending on uers-settings etc. Telerik OpenAccess ORM helps achieving forward mapping with a user-friendly wizard.

Forward mapping is described in more details in the related topic for using the Forward Mapping Wizard.

 

Reverse Mapping

The Reverse-Mapping approach is about defining a data model starting from designing a database-schema. Telerik OpenAcces ORM reads an already defined database schema and generates Classes for the tables, columns get mapped to fields of the classes, join-tables or many-to-many relations get mapped to collection fields etc.

Many options for the class generation are available in the wizard for this scenario. Refer to the related topic for a step-by-step guide on using Reverse-Mapping-Wizard.
