    Note over UniBee: Transaction event occurs
    UniBee->>Client: Send Webhook notification
    Client->>DB: Store data in local database
    Client->>UniBee: Return confirmation response
    
    Note over Client,DB: Real-time data sync completed
```

**Use Cases:**

* Enterprises looking to reduce operational costs
* Organizations requiring professional data hosting
* Businesses with real-time data synchronization requirements

## Selection Recommendations

| Considerations    | Opensource                | Cloud               |
| ----------------- | ------------------------- | ------------------- |
| Data Control      | Complete control          | Sync via Webhook    |
| Operational Cost  | Self-maintenance required | Hosted service      |
| Data Sovereignty  | Fully compliant           | Requires evaluation |
| Technical Barrier | Higher                    | Lower               |
| Real-time Access  | Direct access             | Via Webhook         |

Choose the appropriate deployment mode based on your specific requirements. If you have strict data sovereignty requirements, we recommend choosing the Opensource version; if you want to reduce operational burden and obtain professional data hosting services, the Cloud version is a better choice.
