This document discusses using Perl and the OpenERP object-oriented mapper (OOM) module to interact with the OpenERP ERP system. It provides an overview of the OpenERP object model and API, and describes how to define schemas and classes in Perl that map to OpenERP models. Code examples are given for creating, updating, searching for, and relating objects using the OOM module to interface with an OpenERP database from Perl applications and business logic.
