depth가 2단계의 상속관계를 셋팅하는 경우 id는 최상위 엔티티의 id를 모두 공유하는 방식으로 설계를 해야 할까요?예를 들어 A가 최상위 A를 상속하는 AA, BB 그리고 다시 AA를 상속하는 AAA, BBB. CCC가 있다면 AAA를 만드는 경우 A의 id를 AA, AAA모두가 공유하는 방식이어야 하는건가요?

안녕하세요. JPA 활용 강의를 들으며 추가로 REST API에 대해 공부중입니다.@Controller에서 페이지 렌더링을 하고,@RestController에서 API를 작성하는 것은 이해했습니다. 그러나 model로만 데이터를 넘기다가 API에 대해 공부를하다보니 호출 방식에 대해 이해가 되지 않습니다. 만약에 회원조회 기능을 만든다고 가정하면[1]@RestController에서 /api/members에서 회원 조회하여 ResponseEntity<MemberDto>를 리턴해주고,@Controller에서 /api/members를 호출한 다음에 MemberDto로 변경하여 Model에 담은 후 /memberList로 렌더링 [2]@Controller에서 /memberList로 렌더링한 후, javascript에서 fetch()를 사용하여 /api/members를 호출하여 가져온 값을 화면에 뿌려줌  제가 고민해본 방식은 위 2가지입니다... 올바른 방식이 있는지,, 없다면 어떤 방식이 맞는 지 조언 해주시면 감사하겠습니다...  ========================================앗 해당 질문글을 작성한 후 더 공부를 해보았는데요,CSR (클라이언트 사이드 렌더링)와 SSR (서버 사이드 렌더링) 방식으로 두 가지 방식 모두 존재하는 방식이었군요... (제가 고민해본 방식과 CSR, SSR가 동일한 방식인지는 모르겠습니다... 맞나요...?) 페이지 이동과 동시에 조회가 필요한 곳인 경우 (필터 없이 회원조회) = 페이지 렌더링할때 api를 호출하여 model에 담아 넘기고, 필터로 조회하는 경우 = API만 호출하여 데이터 보여주기 위에 내용으로 개발하면 될까요?? (저는 현재 백엔드 개발자를 준비하며 혼자서 포트폴리오용 프로젝트를 만들고있습니다!)
