# 測試資料庫 { #testing-a-database }

你可以在 [SQLModel 文件](https://sqlmodel.tiangolo.com/) 中學習關於資料庫、SQL 與 SQLModel。 🤓

有一個迷你 [將 SQLModel 與 FastAPI 搭配使用的教學](https://sqlmodel.tiangolo.com/tutorial/fastapi/)。 ✨

# 데이터베이스 테스트하기 { #testing-a-database }

데이터베이스, SQL, SQLModel에 대해서는 [SQLModel 문서](https://sqlmodel.tiangolo.com/)에서 학습할 수 있습니다. 🤓

[FastAPI에서 SQLModel을 사용하는 방법에 대한 미니 튜토리얼](https://sqlmodel.tiangolo.com/tutorial/fastapi/)도 있습니다. ✨

Pages](https://kubernetes.io/docs/tasks/manage-hugepages/scheduling-hugepages/), which allows pods to consume either 2Mi or 1Gi Huge Pages.  This benefits applications that consume large amounts of memory.  Use of Huge Pages is a common tuning recommendation for databases and JVMs.  Finally, the [Device Plugin](https://kubernetes.io/docs/concepts/cluster-administration/device-plugins/) feature, which provides a framework for vendors to advertise their resources to the Kubelet without changing Kubernetes core code....
