4.4 Databases
Databases are one of the most common business applications of computers. Every company has an employee database for keeping track of its personnel, and schools have databases to keep track of their students. There are also many specialized databases for particular applications. For example, libraries place their card catalogs online to make it easy to search for books by title, author, subject matter, or keywords. Also, the Web has telephone directory databases that allow people to look up phone numbers easily. A Web search engine is also a kind of database.
