Como SQLModel se basa en SQLAlchemy, puedes usar fácilmente **cualquier base de datos soportada** por SQLAlchemy (lo que las hace también soportadas por SQLModel), como:

* 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.

    /** Session service error class */
    public static final int ERR_SSN_SRVC = 0x02;

    // name service error codes
    /** Format error in the name service */
    public static final int FMT_ERR = 0x1;
    /** Server error in the name service */
    public static final int SRV_ERR = 0x2;
    /** Implementation error in the name service */
    public static final int IMP_ERR = 0x4;
    /** Refused error in the name service */

En esta sección veremos cómo usar otros middlewares.

## Agregando middlewares ASGI

Como **FastAPI** está basado en Starlette e implementa la especificación <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>, puedes usar cualquier middleware ASGI.

Un middleware no tiene que estar hecho para FastAPI o Starlette para funcionar, siempre que siga la especificación ASGI.
