I propose to show OpenObject in action, how you can customize or develop new modules for OpenERP. It includes: the object and view editor, the workflow editor and the report designer. OpenERP is a modern Enterprise Management Software, released under the AGPL license, and featuring CRM, HR, Sales, Accounting, Manufacturing, Stock. It is based on OpenObject, a modular, scalable, and intuitive Rapid Application Development (RAD) framework written in Python. OpenObject features a complete and modular toolbox for quickly building applications: integrated Object-Relationship Mapping (ORM) support, template-based Model-View-Controller (MVC) interfaces, a report generation system, automated internationalization, and much more.
