"Inventario.php" includes the template for a new class which contains/implements the SQL query necessary for extracting all the products' names, as well as the names of their sellers, data which is then accessed from the API via a GET request sent from an external client.

The "Database.php" file contains a class instantiated to establish a connection with the WordPress database, or alternatively with a private server generated locally through the XAMPP app on Miguel's computer.
