-- Restaurant Database Management System
--
-- Instructions:
-- 1. Create all required tables.
-- 2. Design appropriate PRIMARY KEY and FOREIGN KEY relationships.
-- 3. Add suitable constraints based on the requirements.
-- 4. Insert initial mock data.
-- 5. Insert at least 3 menu items.
-- 6. The script should be executable from start to finish without errors.
-- Workshop 10 - Database Schema & Initial Data
-- پاک کردن جدول‌های قدیمی در صورت وجود (به ترتیب برعکس وابستگی برای جلوگیری از ارور Foreign Key)
