The view is virtual table created from the base table and they don't have physical existence in the database. it contains rows and columns like a real table. 
 views are used for security purpose, for ex. u have a data of US employee like emp_id, emp_name, emp_department and their emp_SSNNo.....now u dont want to show the SSN number to the user u can hide it using views means u are keeping it secure and hiding confidential info.
