Notice the Check this box to evaluate Odoo box. If you mark this checkbox when you create a database, Odoo will preload your tables with a host of sample data for each module that is installed. This may include fake customers, suppliers, sales orders, invoices, inbox messages, stock moves, and products. The purpose of the demonstration data is to allow you to run modules through their paces without having to key in a ton of test data.

You should only use the demonstration data for trying out Odoo. You should never load demonstration data if you plan to use the database for a production environment.

For the purposes of our real-world case study in this book, do not load demonstration data.
