+## 💾 Database Storage & Access
+
+### PostgreSQL Database Storage
+The database files are stored in a Docker volume for persistence across container restarts.
+
+**Docker Volume:** `forge-ai_postgres_data`  
+**Physical Location:** `/var/lib/docker/volumes/forge-ai_postgres_data/_data`
+
+*Note: On macOS, this is inside Docker Desktop's Linux VM and managed automatically.*
+
+### Database Connection Info
+- **Host:** `localhost` (from your Mac)
+- **Port:** `5452` (mapped from container's 5432)
+- **Database:** `forge_ai`
+- **User:** `forge_user`
+- **Password:** `forge_secure_password_2024`
+
+### Accessing the Database
+
+**1. Via Docker exec (Interactive SQL):**
+```bash
+docker exec -it forge-postgres psql -U forge_user -d forge_ai
+```
+
+**2. Backup the Database:**
+```bash
+docker exec forge-postgres pg_dump -U forge_user forge_ai > backup.sql
+```
+
+**3. Restore from Backup:**
+```bash
+cat backup.sql | docker exec -i forge-postgres psql -U forge_user -d forge_ai
+```
+
+**4. View Volume Information:**
+```bash
+docker volume inspect forge-ai_postgres_data
+```
+
+### Other Storage Locations
+- **Uploaded Files/Assets:** `./storage` (in your project directory)
+- **Redis Data:** `forge-ai_redis_data` Docker volume
+- **Celery Task Queue:** Managed by Redis (in-memory)
