    Ao ter o tipo como `int | None`, o SQLModel saberá que essa coluna deve ser um `INTEGER` no banco de dados SQL e que ela deve ser `NULLABLE`.

* `Field(index=True)` informa ao SQLModel que ele deve criar um **índice SQL** para essa coluna, o que permitirá buscas mais rápidas no banco de dados ao ler dados filtrados por essa coluna.
