 **데이터 흐름 관리 시스템**을 통해 ERP 시스템의 화면들 간 데이터 흐름을 시각적으로 설계하고 관리할 수 있습니다. React Flow 라이브러리를 활용한 직관적인 노드 기반 인터페이스와 회사별 권한 관리, 기존 화면관리 시스템과의 완벽한 연동을 통해 체계적인 데이터 관계 관리가 가능합니다.

+## 📊 구현 현황
+
+### ✅ Phase 1 완료 (2024-12-19)
+
+**구현된 기능:**
+
+- React Flow 12.8.4 기반 시각적 캔버스
+- 화면 노드 컴포넌트 (필드 정보, 타입별 색상 구분)
+- 커스텀 엣지 컴포넌트 (관계 타입별 스타일링)
+- 드래그앤드롭 노드 배치 및 연결
+- 줌, 팬, 미니맵 등 고급 시각화 기능
+- 샘플 데이터 생성 및 관리 기능
+- /admin/dataflow 경로 설정
+- 메뉴 시스템 연동 준비 완료
+
+**구현된 파일:**
+
+- `frontend/components/dataflow/DataFlowDesigner.tsx`
+- `frontend/components/dataflow/ScreenNode.tsx`
+- `frontend/components/dataflow/CustomEdge.tsx`
+- `frontend/app/(main)/admin/dataflow/page.tsx`
+- `docs/add_dataflow_menu.sql` (메뉴 추가 스크립트)
+
+**다음 단계:** Phase 2 - 관계 설정 기능 구현
+
 ### 주요 가치

 - **React Flow 기반 시각적 설계**: 복잡한 데이터 관계를 직관적인 노드와 엣지로 설계
