// If a group is passed, it returns policies associated with the group.
//
// If a user is passed, it returns policies of the user along with any groups
// that the server knows the user is a member of.
//
// In LDAP users mode, the server does not store any group membership
// information in IAM (i.e sys.iam*Map) - this info is stored only in the STS
// generated credentials. Thus we skip looking up group memberships, user map,

Justo antes de decidir construir **FastAPI** encontré **APIStar** server. Tenía casi todo lo que estaba buscando y tenía un gran diseño.

// validateReplicationDestination returns error if replication destination bucket missing or not configured

SQLModel은 SQLAlchemy를 기반으로 하므로, SQLAlchemy에서 **지원하는 모든 데이터베이스**를 손쉽게 사용할 수 있습니다(SQLModel에서도 동일하게 지원됩니다). 예를 들면:

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server 등.

이 예제에서는 **SQLite**를 사용합니다. SQLite는 단일 파일을 사용하고 파이썬에서 기본적으로 지원하기 때문입니다. 따라서 이 예제를 그대로 복사하여 실행할 수 있습니다.

나중에 실제 프로덕션 애플리케이션에서는 **PostgreSQL**과 같은 데이터베이스 서버를 사용하는 것이 좋습니다.
