+## 🗄️ External Database Setup
+
+### Database Requirements
+- **MySQL 8.0+** or **MariaDB 10.5+**
+- **Network Access**: Container must be able to reach database host
+- **Schema**: Run `backend/migrate_complete.sql` to create database schema
+- **Permissions**: User needs CREATE, SELECT, INSERT, UPDATE, DELETE privileges
+
+### Database Setup Steps
+```bash
+# 1. Create database
+mysql -u root -p -e "CREATE DATABASE inventory_db;"
+
+# 2. Create user
+mysql -u root -p -e "CREATE USER 'inventory_db'@'%' IDENTIFIED BY 'your_password';"
+
+# 3. Grant permissions
+mysql -u root -p -e "GRANT ALL PRIVILEGES ON inventory_db.* TO 'inventory_db'@'%';"
+
+# 4. Import schema
+mysql -u inventory_db -p inventory_db < backend/migrate_complete.sql
+
+# 5. Flush privileges
+mysql -u root -p -e "FLUSH PRIVILEGES;"
+```
