Actors:
1. Patient/User: This is the primary actor interacting with the system. The patient can perform various actions such as logging in, uploading documents, generating reports, and verifying their information.
2. Database: The database is responsible for storing user credentials and health-related data. It interacts with the login and verification processes.
3. Server: The server handles requests from the user, particularly for uploading documents and generating reports.

Use Cases:
1. Login: 
The patient provides a Username and Password to access the system. Both are essential components of the login process, as indicated by the <<include>> relationship.
   
2. Verification:
After logging in, the system verifies the user's information with the database to ensure the login credentials are correct and to grant further access to other features.

3. Upload Document:
   - The patient can upload health-related documents (such as medical records or test results). The uploaded documents are processed by the server and stored in the database for future reference.

4. Generate Report:
The user can generate a health report based on their uploaded documents and health data. The server processes this request and retrieves the necessary information from the database.\

The above diagram shows the flow of actions, from the user logging into the system to uploading documents and generating reports, all while interacting with both the server and database for smooth operations. It reflects the key functions of the Hello Doctor application in terms of patient data management and health reporting.
