2020-04-28 저장 예제만들어 복습

오늘은 저장 예제를 만들어 이해가 전혀안가는 구간 복습을 했다.

어제 분명 복습하다가 저장에서 뇌정지가 왔기 때문에, 오늘 강사님께 질문한 결과

내생각이 마치 0.5평도안되는 1칸짜리 배열로 정의된 정적인 방에 갇혀있었다는 생각이 들었다.

왜 json파일을 직렬화 하는데 더러운 배열형태로 꼭 만들어서 저장을 해야한다고 생각했을까?

 

강사님의 말씀 중 Key와 Value값만 있으면 그타입이 무엇이든지 저장된다는 말에 머릿속이 바로 클리어됐다.

완벽하게 이해를 했다...사실 질문하다가 제가 아주 잘못 생각하고 있었다는걸 깨달았습니다ㅎㅎㅎ 

그리고 이번일로 항상 문제를 겪을때마다, 그 한 곳에 집중해 크게 못보는 버릇이 있다는 사실도 깨달았다...

 

머릿속에 한참 머물고 있었던게 시원하게 뻥뚫렸기 때문에 오늘 복습은 꼭 데이터매니져를 응용해서 해보고 싶었다.

코드를 열심히 치고 저장된 json을 보며 아니나 다를까, 정말 완벽히 이해가 됐다고 생각한다.

희노애락중 노*10000000000000000000000000000000000 와같던 데이터매니져여...안녕ㅋ

 

.테이블만들기 귀찮아서 그냥 값넣음.
