What is a view?

• In the database views are defined as the “Virtual table (s)” and also known as the stored queries. These tables are not the real tables in the database, but these are like the virtual tables which contain the columns and data like the other real tables. These views are created from one or more than one tables to store the columns and data in it. These tables not contain any kind of data in it, but views are generally created with the set of queries to store the data in it like the other real table as the object stored in the database. After creating the views from the other tables, views always refer these tables all the time for representing the data which is mentioned in the query at the time of execution.
  Views are used for the various purposes.
