3.2 Screenshots of the First Sample Application

When the user invokes the application, the first page prompts the user to enter an employee ID.

When the user clicks the Query Employee button, the application queries the database for the specified employee ID. If found, the application displays information for that employee, including which benefits the employee has currently elected. This is displayed in Figure 3-1:

The user selects which benefits to add or remove, and clicks the Add Selected Benefits or Remove Selected Benefits button.
