You mean real-life examples? Employee databases are usually arrays of records which usually use strings of one sort or another for things like names and addresses. Those are arrays too. Getting back to the records I heard an IT guy at an HR office cussing out an intern because she'd used pointers. I know it's not my place to say anything but when I went back to school I learned just how many ways you can mess up with pointers (somebody told me my use of them is surprisingly good with the implication that I don't inspire confidence in a lot of people to do that. I just took that as a compliment and congratulated myself that nobody's said what the IT guy saiid about me). SQL uses arrays.
