+## 💸 객체지향 개념을 활용하여 은행 구현해보기
+
+## 기능 명세
+
+### 사용자
+
+- [x] 회원가입
+- [x] 입금
+- [x] 출금
+
+### 계좌
+
+- [x] 계좌 개설
+- [x] 계좌번호 랜덤 생성 기능
+
+## 객체들의 역할 -> SRP
+
+- 하나의 객체가 하나의 역할만 하도록 역할을 분리
+
+### Account 관련
+
+1. Account : 계좌에 대하여 정의
+2. AccountRepository : 계좌 관련 DB 저장 및 조회
+3. AccountType : 계좌의 종류에 대하여 정의
+4. TransactionType : 계좌를 이용한 거래의 종류에 대하여 정의
+5. AccountRegisterDto : 계좌를 등록할 시에 사용하는 dto
+6. AccountService : 저축 계좌, 입출금 계좌에 공통적으로 사용되는 비지니스 로직 명시
+7. ChequingAccountService : 입출금 계좌에 사용되는 비지니스 로직 구현
+8. SavingsAccountService : 저축계좌에 사용되는 비지니스 로직 구현
+9. AccountController : 클라이언트로부터 들어온 계좌 관련 요청을 처리
+10. LogGenerator : 계좌 거래 기록을 위해 일정한 형태로 가공
+11. NumberGenerator : 계좌번호를 난수로 생성
+
+### User 관련
+
+1. User : 사용자에 대하여 정의
+2. UserRepository : 사용자 관련 DB 저장 및 조회
+3. UserService : 사용자 관련 비지니스 로직 구현
+4. UserRegisterDto : 사용자 등록 시에 사용하는 dto
+5. UserController : 클라이언트로부터 들어온 사용자 관련 요청을 처리
+
+### 기타
+
+1. CommandSign : 사용자의 입력값의 의미와 사인에 대하여 저장
+2. BankController : 클라이언트의 요청을 처리
+3. BankView : 입출력
+
+## 활용 개념
+
+1. 캡슐화
+
+- UserRegisterDto, AccountRegisterDto: Dto 를 이용하여 클라이언트의 입력값을 캡슐화
+
+1. 변경될 필요가 없는 파라미터에 안정성을 위해 final 키워드 사용
+2. 전역적으로 접근할 수 있는 상수는 static final 이용
+ - 계좌번호 관련 정보, 계좌 개설 가능 연령
+ - 클라이언트가 입력하는 입력값에 대한 정보
+3. 다형성
+ - 계좌를 저축 / 입출금 계좌로 나누어 인터페이스에 정의된 register, deposit, withdraw 와 같은 공통적인 메서드들을 계좌의 타입에 따라서 다르게 구현
+4. 추상화
+
+- 인터페이스를 이용하여 저축 / 입출금 계좌에서 필요한 공통적인 메서드들을 정의
+
+5. 리스코브 치환의 원칙
+
+- SavingsAccountService, ChequingAccountService 모두 AccountService로 대체될 수 있음
