## 📊 Data Structure

### Hero Slider Fields
```
Primary Data:
├── Title (required)
├── Subtitle (required)
├── Tag / Category
└── Image URL

Call-to-Action:
├── Button 1 Text & URL

```

---

## 🌐 Database Integration

### Automatic Table Creation
When API is first accessed, it automatically creates:
```sql
CREATE TABLE hero_sliders (
    id INT AUTO_INCREMENT PRIMARY KEY,
    tag VARCHAR(100),
    title VARCHAR(255) NOT NULL,
    subtitle TEXT NOT NULL,
    button1_text VARCHAR(100),
    button1_url VARCHAR(255),
    button2_text VARCHAR(100),
    button2_url VARCHAR(255),
    image_url VARCHAR(255),
    stat1_icon VARCHAR(100),
    stat1_text VARCHAR(255),
    stat2_icon VARCHAR(100),
    stat2_text VARCHAR(255),
    display_order INT DEFAULT 0,
    status ENUM('active','inactive') DEFAULT 'active',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)
```

### Query Performance
- Indexed by `id` (primary key)
- Efficiently ordered by `display_order`
- Filtered by `status` in queries
- Timestamps tracked automatically
- No migration needed - full backwards compatibility
