Chapter 5. Creating, Listing, and Deleting Names of Customers

In the previous chapter, we created a Data Model and Data objects for the Customer entity. In this chapter, we will learn how to save, display, and delete a customer's information. The information of the customer will comprise of the customer's name, his/her e-mail address, and contact number, and will be stored in the Customer entity.

Recall that we created a project with the name prob in the last chapter and used the Navigation-based Application project template for doing so. The project template, as we know, provides default code in the form of auto-generated files that are required in developing the application. Let us now use the knowledge that we have gained so far to do something practical. Let us see how to create, read, update, and delete records of a customer entity.
