+*** Database class
+Utilizza PDO per effettuare la connessione al server mariadb in esecuzione nel docker container.
+Sia le credenziali di accesso al database che il domain service name (DSN) sono salvate nel file "www/.env" (vedi [[./www/.env.example][.env.example]]) e per leggerle si utilizza il package [[https://github.com/vlucas/phpdotenv][phpdotenv]].
+
+Installazione:
+#+begin_src bash
+cd www
+composer require vlucas/phpdotenv
+#+end_src
+
+** Migrations
+Contengono i cambiamenti efftuati in ordine sul database.
+/Formato migration: touch "m_$(date +%s)_name.php"/
+
 ** Models
 Le classi "Model" gestiscono i dati presenti nel database e controlla che i dati seguano delle determinate regole.
 Tutte le classi Model derivano dalla classe "BaseModel".
