-- JPA란?
-
-  JPA(Java Persistence API)란, **자바 진영에서 ORM(Object-Relational Mapping) 기술의 표준스펙.**
-
-  실제 구현체는 Hibernatem EclipseLink 등이 있고, 스프링 부트에선 보통 Hibernate를 기본 구현체로 사용.
-
-- N+1 문제란?
-
-  1번의 쿼리로 N개의 데이터를 가져왔는데, 연관된 데이터를 채우기 위해 추가로 N번의 쿼리가 실행되는 현상을 말함
-
-  발생과정
-
-    1. 최초쿼리 (1) : `SELECT * FROM Member` 를 실행해 10명의 회원을 가져옴
-    2. 연관 데이터 조회(N) :  즉시 로딩 설정이 되어 있다면, JPA는 각 회원(10명)이 가진 팀(Team) 정보를 채우기 위해 회원별로 팀 조회 쿼리를 각각 날림
-    3. 결과 : 쿼리 1번으로 끝날일이 총 11번(1 + 10) 호출되어 DB 성능이 저하됨
-
-- 지연로딩과 즉시로딩의 차이는?
-
-  지연 로딩
-
-    - 필요할 때 까지 미룬다
-    - 엔티티 조회할 때 연관된 객체는 가져오지 않고, 실제 그 데이터를 사용하는 시점에 DB를 조회함
-    - 동작 방식 : 조회 시점에 연관된 객체 자리에 프록시라는 가짜 객체를 넣어둠. 실제로 연관객체의 내부 데이터에 접근할 때 SQL이 실행.
-    - 어노테이션 : `ManyToOne(fetch=FetchType.LAZY)`
-    - 단점 : 연관된 데이터가 필요 없는 경우 불필요한 조인이나 쿼리를 줄여 성능 최적화 가능
-
-  즉시 로딩
-
-    - 한번에 다 가져온다
-    - 동작 방식 : JPA 구현체는 대개 SQL의 JOIN을 사용하여 한번의 쿼리로 모든 객체를 즉시 함께 조회
-    - 어노테이션 : `@ManyToOne(fetch = FetchType.EAGER)`
-    - 단점 : 연관된 테이블이 많아질수록 쿼리가 복잡해지고, N + 1 문제를 발생시켜 성능 저하의 주범이 됨
-
-- JPQL란?
-
-  엔티티 객체를 대상으로 쿼리하는 객체지향 쿼리 언어(단순히 JPA SQL)
-
-    - 객체지향 쿼리 : 테이블 컬럼명이 아니라 엔티티의 필드(변수)이름을 사용해 쿼리를 작성함
-
-  왜 사용할까?
-
-    - JPA의 기본 메서드 (find())는 식별자로 조회할 때 유용하지만 복잡한 검색조건을 처리하기엔 한계가 있음.
-    - 코드는 자바객체인데 쿼리는 테이블 기준이면 싱크가 깨짐. JPQL은 자바 클래스와 필드 이름을 그대로 쓰기 때문에 훨씬 직관적
-    - 이를 해결하기 위해 SQL의 장점을 가져오면서 객체 지향의 이점을 유지하는 JPQL을 사용.
-
-- Fetch Join란?
-
-  연관된 엔티티나 컬렉션을 SQL 한번에 함께 조회하는 방법
-
-    1. 일반 Join VS Fetch Join
-    - **일반 Join**
-        - 동작 : SQL 상에서는 조인이 일어나지만, JPQL은 SELECT절에 명시된 엔티티만 조회
-        - 결과 : 연관된 엔티티는 프록시가 상태로 남아있어, 나중에 접근할 때 추가쿼리가 발생
-    - **Fetch Join**
-        - 동작 : SQL 조인을 실행하면서 연관된 엔티티의 데이터까지 한번에 SELECT해서 가져옴.
-        - 결과 : 연관된 엔티티가 프록시가 아닌 실제 엔티티로 채워진 상태로 조회됨. 따라서 추가쿼리 없이 데이터를 바로 사용할 수 있음.
-
-- @EntityGraph란?
-
-  Fetch 조인을 보완하기 위해 나온 기능. 쿼리 수행 시점에 연관된 엔티티들을 함께 조회하도록 설정하는 어노테이션
-
-    - 사용 이유
-        - JPQL의 Fetch Join은 쿼리문 안에 조인코드를 직접 작성해야 한다는 번거로움이 있음.
-        - 코드의 간결함 : 스프링 부트 JPA를 사용하면 메서드 위에 어노테이션 하나만 붙여서 N + 1 문제를 해결할 수 있음.
-        - 쿼리분리 : 똑같은 findAll()이라도 어떤 메서드에서는 연관데이터를 가져오고, 어떤 메서드에서는 안 가져오게끔 유연히 관리 가능
-
-- commit과 flush 차이점은?
-    - Flush (플러시) : 영속성 컨텍스트의 변경 내용을 데이터베이스에 동기화하는 작업
-        - 하는일 : 쓰기 지연 SQL 저장소에 쌓여있던 INSERT, UPDATE, DELETE 쿼리를 DB로 보냄
-        - 영향 : 쿼리가 DB로 전송되지만, DB 입장에서는 아직 임시 쿼리 상태임. 다른 트랜잭션에선 이 데이터를 못 봄
-        - 영속성 컨텍스트 유지 : 플러시가 일어나도 영속성 컨텍스트 내의 엔티티들은 지워지지 않고 그대로 유지.
-        - 발생시점
-            1. em.flush() 직접 호출
-            2. 트랜잭션 커밋 시
-            3. JPQL 쿼리 실행 시
-    - Commit (커밋) : 데이터베이스의 트랜잭션을 종료하고 변경사항을 영구적으로 반영하는 작업
-        - 하는일 : 내부적으로 em.flush()를 먼저 호출해 쿼리를 보낸 후 DB에 커밋 명령을 내림
-        - 영향 : 데이터가 실제로 DB에 저장되며, 다른 사용자나 시스템에서도 변경된 데이터를 조회할 수 있게됨
-        - 트랜잭션 종료 : 커밋이 완료되면 해당 트랜잭션이 완전히 종료.

+- Spring Security가 무엇인가?
+
+  스프링 기반 애플리케이션의 보안을 담당하는 강력하고 포괄적인 하위 프레임워크
+
+  복잡한 보안 로직을 직접 구현할 필요 없이 표준화된 필터 기반의 설정을 통해 시스템을 안전하게 보호한다.
+
+- 인증(Authentication)vs 인가(Authorization)
+
+  비슷해보이지만 서로 다른 개념이다.
+
+  인증 (Authentication)
+
+    - 본인확인 절차
+    - 사용자가 자신이 주장하는 사람이 맞는지 확인하는 과정
+
+  인가 (Authorization)
+
+    - 권한확인 절차
+    - 인증된 사용자가 특정 리소스에 접근할 수 있는 권한이 있는지 확인하는 과정
+
+- Stateful vs Stateless
+
+  논점 : 서버가 클라이언트의 세션 정보를 기억하는가?
+
+  Stateful(상태유지) : 세션 정보를 기억함
+
+  Stateless(토큰 기반) : 서버가 상태를 유지하지 않으므로 요청에 포함된 토큰(JWT)로 검증
+
+  | 구분 | Stateful | Stateless |
+      | --- | --- | --- |
+  | 특징 | 서버가 세션 저장소에 로그인 상태 유지 | 서버가 상태를 유지하지 않음, 요청에 포함된 토큰으로 검증 |
+  | 인증방식 | JSESSION쿠키를 통해 서버 메모리/DB의 세션 조회 | 매 요청시 HTTP헤더에 토큰을 담아서 전송 (Authorization:Bearer<token>) |
+  | 서버 확장 | 세션 불일치 문제 발생 가능 | 각 요청이 독립적이므로 서버 증설에 유리 |
+  | 메모리 및 비용 | 동시접속자가 많을수록 서버 세션 메모리 소비 증가 | 토큰 검증 연산이 필요하며, 서버 메모리 사용량은 적음 |
+  | 주요 활용처 | 전톤적인 웹 애플리케이션 | REST API, 모바일 앱, MSA |
+
+  서버 확장 방법
+
+    - Scale-up : 단일 서버 성능 향상
+    - Scale-out : 서버의 개수를 늘리기
+    - 로드밸런서 : 서버 부하를 분산시키는 H/W, S/W
+        - 클라이언트와 서버Pool 사이에 위치해 서버의 부하를 분산시키는 하드웨어나 S/W
