Chapter 4 Question 9

9. Why are forms (input screens) important in a relational database?

In looking at the tables and data, it is clear that the tables are connected through primary keys. But you cannot expect users or managers to memorize and enter primary keys (for example, CustomerID in an Order). So, forms are used to create an image of the underlying business application, with tools like select boxes to make it easy to enter data from lists.
