Enhancing our sample application

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

While we want to have a realistic design in our sample application, we will make changes that illustrate the main (and what we feel are the most important) features in NAV table design. If there are capabilities or functionality that you feel is missing, then feel free to add them. Adjust the examples as much as you wish to make them more meaningful to you.

Our new data fields are shown in the following table...
