New customers pour into the video rental store every day. These new customers must be added to the set of customers in the database. In our model, a store employee types new customer information into a screen-based new customer form. To enhance cross-platform portability and simplify the tutorial code, this example program reads in the new customer data from a file.

Like the previous examples, this tutorial uses the VVContact and VVContactRepository classes, which encapsulate most of the functionality of this example. These classes hide the details of the DB Interface Module code in the same manner that the DB Interface Module code hides the details of the underlying database API.
