Enhancing the Trip Maintenance application

In this lesson, you will make enhancements to the sample Trip Maintenance application that you
created in previous lessons. In
buttons to the Trip Detail page to browse, add, edit, delete or search for records in the database.
In this lesson you will build the action pages that implement the actions for these buttons.
Page flow
You will combine the Trip Detail page and the search pages you built in the previous lessons with
a maintenance action page and a navigation action page you will build in this lesson. In the final
two lessons you will build a Trip Edit page to complete the trip maintenance facility. The
following figure shows the flow of the finished Trip Maintenance application pages:

Navigation Action page
Notice that the Trip Detail page is at the center of the Trip Maintenance application. Depending
on the user action, the Trip Detail page navigates the records in the database or connects to the
appropriate page to add, edit, delete, or search for records in the database.
In order for the application to process the user actions from the Trip Detail page, you must build
the two action pages for the navigation and maintenance functions.
Navigation action page
This navigation action page determines which triprecord displays on the Trip Detail page after
the user presses one of the navigation buttons. There is no HTML output displayed from this
action page. Instead, this page uses dynamic SQL to identify the
Trip Detail page. In this dynamic SQL statement the proper
the URL then redirects it to the Trip Detail page.
