/// tip | Подсказка

Вы можете использовать любую другую библиотеку для работы с SQL или NoSQL базами данных (иногда их называют <abbr title="Object Relational Mapper – Объектно-реляционный маппер: термин для библиотеки, где некоторые классы представляют SQL-таблицы, а экземпляры представляют строки в этих таблицах">"ORMs"</abbr>), FastAPI ничего не навязывает. 😎

///

/// tip

您可以使用任何其他您想要的 SQL 或 NoSQL 数据库（在某些情况下称为 <abbr title="对象关系映射器（Object Relational Mapper，ORM），一个术语，用来指代一种库，其中某些类对应于 SQL 数据表，这些类的实例则对应于表中的行。">“ORM”</abbr>），FastAPI 不会强迫您使用任何东西。😎

由于 SQLModel 基于 SQLAlchemy，因此您可以轻松使用任何由 SQLAlchemy **支持的数据库**（这也让它们被 SQLModel 支持），例如：

* PostgreSQL
* MySQL
* SQLite

  /**
   * On a concurrent computation that throws an unchecked exception, all threads should get the
   * (wrapped) exception, with the loader called only once. The result should not be cached (a later
   * request should call the loader again).

/// tip | Consejo

Puedes usar cualquier otro paquete de bases de datos SQL o NoSQL que quieras (en algunos casos llamadas <abbr title="Object Relational Mapper – Mapeador Objeto-Relacional: un término elegante para un paquete donde algunas clases representan tablas SQL y las instances representan filas en esas tablas">"ORMs"</abbr>), FastAPI no te obliga a usar nada. 😎

/// tip | 팁

다른 SQL 또는 NoSQL 데이터베이스 라이브러리를 사용할 수도 있습니다 (일부는 <abbr title="객체 관계 매퍼(Object Relational Mapper), SQL 테이블을 나타내는 클래스를 제공하고 테이블의 행을 인스턴스로 표현하는 라이브러리를 지칭하는 용어">"ORM"</abbr>이라고도 불립니다), FastAPI는 특정 라이브러리의 사용을 강요하지 않습니다. 😎
