génère à l'enregistrement*. SQLModel comprend que la base fournira l'`id` et *définit la colonne comme un `INTEGER` non nul* dans le schéma de base. Voir la [documentation SQLModel sur les clés primaires](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id) pour plus de détails.

* `Field(index=True)` indique à SQLModel qu'il doit créer un **index SQL** pour cette colonne, ce qui permettra des recherches plus rapides dans la base lors de la lecture de données filtrées...

* `Field(index=True)`는 SQLModel에 해당 열에 대해 **SQL 인덱스**를 생성하도록 지시합니다. 이를 통해 데이터베이스에서 이 열로 필터링된 데이터를 읽을 때 더 빠르게 조회할 수 있습니다.
