The ORM - Object-relational mapping

The Models

The ORM, short for Object-Relational Mapping, is a central part of OpenERP.

In OpenERP, the data model is described and manipulated through Python classes and objects. It is the ORM job to bridge the gap – as transparently as possible for the developer – between Python and the underlying relational database (PostgreSQL), which will provide the persistence we need for our objects.
