# SQL (관계형) 데이터베이스

**FastAPI**에서 SQL(관계형) 데이터베이스 사용은 필수가 아닙니다. 여러분이 원하는 **어떤 데이터베이스든** 사용할 수 있습니다.

여기서는 <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>을 사용하는 예제를 살펴보겠습니다.

**SQLModel**은 <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a>와 Pydantic을 기반으로 구축되었습니다.SQLModel은 **SQL 데이터베이스**를 사용하는 FastAPI 애플리케이션에 완벽히 어울리도록 **FastAPI**의 제작자가 설계한 도구입니다.
