Enhancing our sample application

Now we can take our knowledge of tables and expand our WDTU application. Our base Radio Show table needs to be added to and modified. We also need to create and reference additional tables.

Although we want to have a realistic design in our sample application, we will focus on changes that illustrate the features in the NAV table design which the authors feel are among the most important. If there are capabilities or functionalities that you feel are missing, feel free to add them. Adjust the examples as much as you wish to make them more meaningful to you.
