Database

A database is like an address book or a recipe box, but you can find and use information much more quickly and powerfully in a computerized database than you can in a paper address book. Let's say you make a contact list in your database that includes checkboxes for whether people are family members, whether you sent them holiday cards, and whether they work at your company or not. In the contact list you also create places (called "fields") where you can type in (called "entering" in computer jargon) birthdates, anniversaries, and the names of their children.

In a paper address book, you would have to flip through all the pages to find the people who have birthdays in October. Using your database, you click a button to find all the people who have birthdays in October. In fact, you can click a button to find all the people who have birthdays in October who also work at your company, live in the neighboring town, and have a child named Ryan.
