- Used JavaScript to trigger API calls and dynamically update the DOM.

3. Database (SQL Server)

- Integrated SQL Server for storing and managing employee data persistently.

4. Application Flow

- Data flows from the user interface to the backend via API calls and reflects instantly on the frontend.

Technical Learnings & Challenges

1. Spring Boot Integration

- Learned how to build REST APIs and connect them with services and repositories.

2. Frontend & DOM Interaction

- Used JavaScript to dynamically display and update data on the web page.
