* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.

/// tip

/// info

This requires installing `ujson` for example with `pip install ujson`.

///

/// warning

`ujson` is less careful than Python's built-in implementation in how it handles some edge-cases.

/// tip

It's possible that `ORJSONResponse` might be a faster alternative.

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

En este ejemplo, usaremos **SQLite**, porque utiliza un solo archivo y Python tiene soporte integrado. Así que puedes copiar este ejemplo y ejecutarlo tal cual.

Más adelante, para tu aplicación en producción, es posible que desees usar un servidor de base de datos como **PostgreSQL**.
