Puedes estudiar sobre bases de datos, SQL y SQLModel en la <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">documentación de SQLModel</a>. 🤓

Hay un mini <a href="https://sqlmodel.tiangolo.com/tutorial/fastapi/" class="external-link" target="_blank">tutorial sobre el uso de SQLModel con FastAPI</a>. ✨

# Bases de Datos SQL (Relacionales) { #sql-relational-databases }

**FastAPI** no requiere que uses una base de datos SQL (relacional). Pero puedes utilizar **cualquier base de datos** que desees.

Aquí veremos un ejemplo usando <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>.
