The next row up shows, in the first three columns, the

data that might describe those three things: Julia Roberts has

the customer name “Julia Roberts,” and a birth date. The

Wall Street Branch has an address and a branch manager.

The checking account has an account number and a monthly

charge. The fourth column shows a particular program,

called anATM controller. This carries out such transactions,

and the cell describes it as a body of program code in the

Java language. These are the things that would concern the

person managing data for the banking business.
