School 모델

이 항목에는 School 샘플 데이터베이스에 대한 개념적 모델, 저장소 모델 및 매핑 정보가 포함되어 있습니다. School 데이터베이스를 만들려면 School 샘플 데이터베이스 만들기를 참조하십시오.

School 모델은 Entity Framework 및 엔터티 데이터 모델 도구 설명서의 예제 코드에 사용됩니다. 개념적 모델, 저장소 모델 및 매핑 정보는 각각 CSDL(개념 스키마 정의 언어), SSDL(저장소 스키마 정의 언어) 및 MSL(매핑 사양 언어)로 표현됩니다. 저장소 모델, 개념적 모델 및 매핑은 Entity Data Model Wizard 또는 edmgen.exe 명령줄 도구를 사용하여 만드는 것이 가장 좋습니다.

참고:
엔터티 데이터 모델 디자이너를 사용하여 School 모델을 확장하는 방법은 ADO.NET Entity Data Model Designer Scenarios를 참조하십시오.
