+## 🧩 아키텍처 설계
+
+본 프로젝트는 API 모듈과 DB 모듈을 분리한 멀티 모듈 구조를 사용합니다.
+
+---
+
+### 📌 모듈 구성
+
+| 모듈 | 설명 |
+|------|------|
+| api-app | API 및 비즈니스 로직 |
+| infrastructure-db-postgres | DB 접근 및 설정 |
+
+---
+
+## 🗄️ Database Module 분리 전략
+
+DB 관련 로직은 별도의 모듈(infrastructure-db-postgres)로 분리되어 관리됩니다.
+
+---
+
+### 🎯 분리 목적
+
+- 기술 의존성 분리
+- DB 교체 용이성
+- 관심사 분리
+- 확장성 확보
+
+---
+
+### 🔄 처리 흐름
+
+Controller → Service → Repository → DB
+
+---
+
+### 💡 설계 포인트
+
+- API 모듈은 DB 기술에 직접 의존하지 않음
+- DB 관련 코드는 별도 모듈에서 관리
+- DB 변경 시 API 코드 수정 최소화
+
+---
+
+## 🔥 한 줄 요약
+
+DB 기술 변경에 유연하게 대응하기 위해 persistence 레이어를 모듈로 분리했습니다.
