Question
In my java class, we need to create a web application using MVC archietecture.First it needs a web page that has a form which need to have first name, last name, yearly salary. When user submit the form it should be able to calculate user's monthly salary by dividing yearly salary by 12.The user information including the yearly and monthly salary will be processed by the system, written to a database table, and the user will be presented with a summary page that lists what was inserted into the database. The database table will have a primary key of the person’s last name. If the database already has an existing entry with the same primary key, the final summary screen will include a note that the user data was not inserted because it was a duplicate. Create a derby database for this lab.
