Explanation

A database is an organized body of information. Libraries have lots of databases to help you find books, articles, or information. Looking for some information? You might need to check a database, probably at the library or online. A database collects a bunch of information and resources, usually on a common subject. Some databases feature newspapers; others are related to legal issues. The police use databases to track criminals, and the government uses databases to track terrorists. Anywhere there's information being collected and accessed, there's probably a database keeping track of it all.
