Preface

Odoo is a full-featured open source platform to build applications. Based on this core framework, a suite of integrated applications was built, covering all business areas from CRM and sales to inventory and accounting.

Beyond these out-of-the-box features, Odoo is an application development framework built with extensibility in mind. Extensions and modifications can be implemented as modules, to be applied over the module with the feature being changed. This avoids editing the original feature code and provides clean and easy-to-control customized applications.

This capability to combine several modules into feature-rich applications, along with the open source nature of Odoo, are important factors that explain the community that grew around Odoo. In fact, there are thousands of community modules available for Odoo, covering virtually every topic.

Odoo 15 Development Essentials provides a step-by-step guide to Odoo development, allowing you to quickly climb the learning curve and become productive on the Odoo application platform. At the same time, it provides good reference materials, to be kept nearby every time you are working with Odoo.
