You could use any other SQL or NoSQL database library you want (in some cases called <abbr title="Object Relational Mapper, a fancy term for a library where some classes represent SQL tables and instances represent rows in those tables">"ORMs"</abbr>), FastAPI doesn't force you to use anything. 😎

///

La especificación de OAuth2 define "scopes" como una lista de strings separados por espacios.

El contenido de cada uno de estos strings puede tener cualquier formato, pero no debe contener espacios.

Estos scopes representan "permisos".

En OpenAPI (por ejemplo, en la documentación de la API), puedes definir "esquemas de seguridad".

Cuando uno de estos esquemas de seguridad usa OAuth2, también puedes declarar y usar scopes.

/// tip

You are free to use each operation (HTTP method) as you wish.

**FastAPI** doesn't enforce any specific meaning.

The information here is presented as a guideline, not a requirement.

For example, when using GraphQL you normally perform all the actions using only `POST` operations.

A especificação OAuth2 define "escopos" como uma lista de strings separadas por espaços.

O conteúdo de cada uma dessas strings pode ter qualquer formato, mas não devem possuir espaços.

Estes escopos representam "permissões".

No OpenAPI (e.g. os documentos da API), você pode definir "esquemas de segurança".

Quando um desses esquemas de segurança utiliza OAuth2, você pode também declarar e utilizar escopos.

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".

In OpenAPI (e.g. the API docs), you can define "security schemes".

When one of these security schemes uses OAuth2, you can also declare and use scopes.

Each "scope" is just a string (without spaces).
