In this chapter, we started by looking at how to activate Odoo's developer mode. Next, we walked through how to make a backup of the Odoo database and how to restore that database using database management tools in Odoo, while emphasizing the importance of creating backups. Next, we went through the step-by-step process of customizing Odoo, looking at how to add fields to the database, and ultimately to your forms and views. This is by no means a comprehensive guide to Odoo customization; it is merely an introduction to common ways of customizing forms, lists, and searches.

In the next chapter, we will explore how we can use the Odoo report designer to customize reports and export data from Odoo. We will begin by looking at how to customize the company headers and footers that appear on documents. With Odoo, we can use dynamic fields to automatically put values from our database into our reports. Using the new QWeb template language, we will get a great deal of power and flexibility when building reports that integrate well with Odoo.
