# SQL (Relational) Databases { #sql-relational-databases }

**FastAPI** doesn't require you to use a SQL (relational) database. But you can use **any database** that you want.

Here we'll see an example using [SQLModel](https://sqlmodel.tiangolo.com/).

**SQLModel** is built on top of [SQLAlchemy](https://www.sqlalchemy.org/) and Pydantic. It was made by the same author of **FastAPI** to be the perfect match for FastAPI applications that need to use **SQL databases**.
