Modify the ATM simulation program of Worked Example 24.1 so that the program pops up two ATM frames. Verify that the database can be accessed simultaneously by two users.

Data from worked example 24.1

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.
