    In many cases, OAuth2 with scopes can be an overkill.

    But if you know you need it, or you are curious, keep reading.

## OAuth2 scopes and OpenAPI

The OAuth2 specification defines "scopes" as a list of strings separated by spaces.

The content of each of these strings can have any format, but should not contain spaces.

These scopes represent "permissions".

Each of these attributes represents a column in its corresponding database table.

We use `Column` from SQLAlchemy as the default value.

And we pass a SQLAlchemy class "type", as `Integer`, `String`, and `Boolean`, that defines the type in the database, as an argument.

```Python hl_lines="1  10-13  21-24"
{!../../../docs_src/sql_databases/sql_app/models.py!}
```
