SQL language enables database system to add new files to database. At the same time SQL also empowers database system to insert data, remove, delete, retrieve and change the already existent files from database.

Consequently database systems are available on machines that range all the way from the smallest handheld device or personal computers to large mainframes. The use of database system is even more important in Internet where data is stored and shared in a large scale.
