+### 📋 **데이터베이스 마이그레이션**
+
+메인 서버에 배포할 때 반드시 실행해야 하는 데이터베이스 마이그레이션:
+
+#### **필수 추가 컬럼들** (materials 테이블)
+```sql
+-- 파이프 사이즈 정보
+ALTER TABLE materials ADD COLUMN IF NOT EXISTS main_nom VARCHAR(50);
+ALTER TABLE materials ADD COLUMN IF NOT EXISTS red_nom VARCHAR(50);
+
+-- 전체 재질명
+ALTER TABLE materials ADD COLUMN IF NOT EXISTS full_material_grade TEXT;
+
+-- 업로드 행 번호
+ALTER TABLE materials ADD COLUMN IF NOT EXISTS row_number INTEGER;
+```
+
+#### **성능 최적화 인덱스**
+```sql
+CREATE INDEX IF NOT EXISTS idx_materials_main_nom ON materials(main_nom);
+CREATE INDEX IF NOT EXISTS idx_materials_red_nom ON materials(red_nom);
+CREATE INDEX IF NOT EXISTS idx_materials_full_material_grade ON materials(full_material_grade);
+```
+
+#### **자동 마이그레이션 스크립트**
+```bash
+# 메인 서버에서 실행
+psql -U tkmp_user -d tk_mp_bom -f backend/scripts/PRODUCTION_MIGRATION.sql
+```
+
+### ⚠️ **중요 사항**
+- 이 컬럼들이 없으면 파일 업로드 시 500 에러 발생
+- 완전 초기화 시: `database/init/99_complete_schema.sql` 사용
+- 기존 서버 업데이트 시: `backend/scripts/PRODUCTION_MIGRATION.sql` 사용
+
+### 🔧 **배포 체크리스트**
+1. [ ] 데이터베이스 백업
+2. [ ] 마이그레이션 스크립트 실행
+3. [ ] 컬럼 존재 확인
+4. [ ] 파일 업로드 테스트
+5. [ ] 자재 분류 기능 테스트
