- 공지사항에 대한 알림 처리와 마케팅에 대한 알림 처리가 각각 다를 수 있다.
- 알림에 대한 성질은 동일하니 슈퍼타입-서브타입을 이용하여 공통된 속성을 상속 받는다.
- 추가적으로, "사용자 간 차단 기능이 생기게 되어 차단 한 사용자가 누른 좋아요는 집계를 하지 않는다."라는 요구사항을 반영해 block 테이블을 생성하고 member 테이블과 1:N 관계로 연결해주었다.
- 서브타입은 하나의 슈퍼타입만을 상속받을 수 있고 슈퍼타입:서브타입은 1:N 관계가 가능하다.
- 추후 데이터 관리 및 유지보수를 위해 테이블마다 created_at, updated_at을 추가하는 게 좋다.
