WORKED EXAMPLE 24.1 Programming a Bank Database In this worked Example, we will develop a complete database program. We will reimplement the ATM simulation of Chapter 14, storing the customer and account data in a database. Recall that in the simulation, every customer has a customer number, a PIN, and two bank accounts: a checking account and a savings account.
