+### Cours 2 - Introduction à l'ORM Doctrine (23/03/2021)
+
+Objectif de l'ORM, lier la structure de la base de données à ses `Entity` php.
+
+Pas besoin de se connecter à la console de la base de données en CLI (dans l'idéal)
+
+Dans l'idéal nous souhaitons tout faire via le code php et la CLI PHP de Symfony.
+
+ **Relations**
+
+- On fera en sorte que l'objet qui a "un seul" va porter la liaison 
+
+*NOTE: Pattern singloton (cf. pour le requêtage à BDD)*
