2. Objectives & Goals

  • Enable users to list all employees in a readable tabular format.
  • Allow users to add new employees with required fields (name, department, salary).
  • Support editing employee details with a pre-filled form.
  • Provide a read-only detailed view of individual employees.
  • Allow deletion of employees with user confirmation.
  • REST API endpoints should support all CRUD operations for integration or future enhancements.
  • The UI should be intuitive with responsive, clear action buttons (View, Edit, Delete).
