SQLModel은 `str`으로 선언된 항목이 SQL 데이터베이스에서 `TEXT` (또는 데이터베이스에 따라 `VARCHAR`) 유형의 열로 저장된다는 것을 인식합니다.

### 엔진 생성하기

SQLModel의 `engine` (내부적으로는 SQLAlchemy `engine`)은 데이터베이스에 대한 **연결을 유지**하는 역할을 합니다.

**하나의 단일 engine 객체**를 통해 코드 전체에서 동일한 데이터베이스에 연결할 수 있습니다.

# OPA Quickstart Guide [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io)

OPA is a lightweight general-purpose policy engine that can be co-located with MinIO server, in this document we talk about how to use OPA HTTP API to authorize requests. It can be used with any type of credentials (STS based like OpenID or LDAP, regular IAM users or service accounts).

OPA is enabled through MinIO's Access Management Plugin feature.
