스킬 DB 내용 중 강의 내용과 공유주신 링크 내용에 차이가 있습니다. 노션에 익숙하지 않아서 헷갈리네요. 4월에 업데이트 된 강의 자료만 참고하면 되나요?

https://n8n.partnerlinks.io/datapopcorn 해당 링크에서 get start를 누르면 강의 화면에 보이는 내용이 아니라 회사 이메일을 입력하는 립력란이 뜨는데, 혹시 그 사이 바뀐 걸까요?회사 이메일 입력한느 곳에 그냥 개인 이메일을 넣어도 되는 건지, 아니면 지금은 이대로 따라하지 않고 [n8n 실습 서버 운영]으로만 가능한 건지 궁금합니다.

안녕하세요. 공통 코드와 계층 구조 관련해서 질문이 있어 질문 드립니다. 이전에 경험했던 프로젝트 보면 공통 코드와 계층 구조 테이블을 다 합친 일명 '만능 코드 테이블' 에 모두 넣고 사용하는 방식도 사용했는데 이번 공통 코드(자연키, 복합키) 강의와, 계층 구조의 강의를 들으며 시야가 또 달라지네요.예를 들면 주문 상태 코드와, 상품 코드를 하나의 테이블의 대체키, 외래키를 적용해서 사용했었네요. 혹시 '만능 코드 테이블'의 경우는 추후 유지보수와 개발 편의 관점에서 개선해야하는 부분이 맞겠지요?만약에 개선하게 된다면, 어떤 기준으로 나누면 될지. 설계적 관점에 대해 혜안을 듣고 싶습니다. 예를 들면, 공통 코드 테이블 2개와, 계층 테이블 이렇게 두고 계층의 가능성으로 보통 나누는지 궁금하고, 추가로 도메인 성격까지 고려해서 테이블을 또 쪼개는지 등이 궁금합니다. 그리고 CS 팀에서 고객 문의 사항에 문의 유형을 최초 상품, 주문, 배송 이런식으로 공통 코드에 넣어서 사용하고 있었는데, 갑자기 정책이 바뀌면서 주문 하위에 주문 오류, 주문 취소 등 하위 개념이 생기면 계층 테이블로 옮겨야 할 거 같은데 이런 경우는 애초에 기획당시에 개발자가 확장 가능성에 대해 고민을 하고 공통 테이블로 넣었으면 안되는 것인지에 대한 부분도 궁금하네요. 매번 질높은 강의로 도움주셔서 감사합니다!

시스템에서 환경변수에 입력이 되었지만파워셀에서 코드확인이 않되네요..어떻게 하면될까요?

안녕하세요!시험장에서 import pandas as pddf = pd.read_csv("~") 각 유형별로 문제를 불러오는 코드는 기본적으로 제공이 되는걸까요? 감사합니다.

안녕하세요 지금 숙박업소를 검색/조회하는 시스템을 만들려고하는데대규모 기반으로 만들어보려고합니다 하지만 문제가 있는데호텔의 가격이 동적데이터일 예정이고, 체크인 체크아웃날짜마다 예약가능객실도 달라질터라elasticsearch와 querydsl을 적절히 혼용하여 사용해야할거 같은데 어떻게 혼용해야할지 고민입니다 keyword=에코 checkIn=2026-06-01 checkOut=2026-06-02 capacityAdult=2 minPrice=15000 grade=5 ▼ ① ES: "에코" → hotelId 목록 (최대 2000개) ▼ ② QueryDSL: WHERE hotel.id IN (esIds) + 날짜 기준 예약가능 여부 (reservation JOIN) + 가격 범위 (room_price JOIN) + 인원, 성급, 숙소유형 + 커서 페이징 ▼ 결과 반환이런식으로 하는게 좋을까요 아니면 es동기화 파이프라인을 만들어서 es에 올인하는게 나을까요?포트폴리오 수준에서 어떻게 해야할지 고민입니다
