| How MySQL Can Help You |
This section describes situations in which the MySQL database system is useful. This will give you an idea of the kinds of things MySQL can do and the ways in which it can help you. If you don't need to be convinced about the usefulness of a database system—perhaps because you've already got a problem in mind and just want to find out how to put MySQL to work helping you solve it—you can proceed to the "A Sample Database" section later in this chapter.
A database system is essentially just a way to manage lists of information. The information can come from a variety of sources. For example, it can represent research data, business records, customer requests, sports statistics, sales reports, personal hobby information, personnel records, bug reports, or student grades. However, although database systems can deal with a wide range of information, you don't use such a system for its own sake. If a job is easy to do already, there's no reason to drag a database into it just to use one. A grocery list is a good example; you write down the items to get, cross them off as you do your shopping, and then throw the list away. It's highly unlikely that you'd use a database for this. Even if you have a palmtop computer, you'd probably keep track of a grocery list by using its notepad function rather than its database capabilities.
