We have learned all the essentials about data serialization, and gained a better understanding of the XML aspects we saw in the previous chapters.

We also spent some time understanding External Identifiers, a central concept for data handling in general, and for module configurations in particular.

XML data files were explained in detail. We learned about the several options available to set values on fields and also to perform actions such as deleting records and calling model methods.

CSV files and the data import/export features were also explained. These are valuable tools for Odoo initial setup or for mass editing of data.

In the next chapter are will explore in detail how to build Odoo models and later learn more about building their user interfaces.
