Defining Data Screens 

Data screens let the user enter data and allow the application to display
information to the user.  Data screens can consist of a combination of
literals, system items, input fields, and display fields.

The data screen you create in this lesson will let the user enter the
information necessary to add, delete, modify, or review records in the
product data file, table, or data set.
