Você pode usar qualquer outra biblioteca de banco de dados SQL ou NoSQL que quiser (em alguns casos chamadas de <abbr title="Object Relational Mapper, um termo sofisticado para uma biblioteca onde algumas classes representam tabelas SQL e instâncias representam linhas nessas tabelas">"ORMs"</abbr>), o FastAPI não obriga você a usar nada. 😎

# Dependencies { #dependencies }

**FastAPI** has a very powerful but intuitive **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection" { #what-is-dependency-injection }

 * factory classes like:
 *
 * <pre>
 * interface Book {...}
 * public class Books {
 *   public static Book hardcover(String title) {...}
 *   public static Book paperback(String title) {...}
 * }
 * </pre>
 *
 * <p>And all the created {@code Book} instances can be tested with:
 *
 * <pre>
 * new ClassSanityTester()
 *     .forAllPublicStaticMethods(Books.class)

## Crea un Entorno Virtual

Cuando empiezas a trabajar en un proyecto de Python **por primera vez**, crea un entorno virtual **<abbr title="hay otras opciones, esto es solo una guía sencilla">dentro de tu proyecto</abbr>**.

/// tip | Consejo

Solo necesitas hacer esto **una vez por proyecto**, no cada vez que trabajas.

## Crie um ambiente virtual

Ao começar a trabalhar em um projeto Python **pela primeira vez**, crie um ambiente virtual **<abbr title="existem outras opções, esta é uma diretriz simples">dentro do seu projeto</abbr>**.

/// tip | Dica

Você só precisa fazer isso **uma vez por projeto**, não toda vez que trabalhar.
