First Module to OpenERP

OpenERP is a Python based client/server program for Enterprise Resource Planning. It consist of a client “openerp-client” and a server “openerp-server” while the persistence is provided by Postgresql. OpenERP currently uses XML-RPC for communication over a network. Once installed OpenERP has a modular structure that allows modules to be added as needed.

The Modules - Introduction

The usage of the modules is the way to extend OpenERP functionality. The default OpenERP installation is organized as a kernel and various modules among which we can distinguish :

• base : The most basic module. Defines ir.property, res.company, res.request, res.currency, res.user, res.partner
• crm : Customer & Supplier Relationship Management.
• sale : Sales Management.
• mrp : Manufacturing Resource Planning.

New modules can be programed easily, and require a little practice of XML and Python.
