+## 🔄 Database Changes
+
+### New Table Created (Auto-Created)
+
+```sql
+CREATE TABLE IF NOT EXISTS warehouse_boxes (
+    id INT AUTO_INCREMENT PRIMARY KEY,
+    box_number VARCHAR(50) UNIQUE NOT NULL,
+    status ENUM('open', 'closed') DEFAULT 'open',
+    location_id INT,
+    description TEXT,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+    FOREIGN KEY (location_id) REFERENCES warehouse_locations(id) ON DELETE SET NULL
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
+```

+
+**Indexes**:
+- Primary key on `id`
