Answer / sreekanth
No, View is a logical table associated with a query.
It will not store any data in it.
Only the query with which the view is created is stored in
the database.

Answer / sekhar
Absolutely, the view contain no data. The basic property of
a view is to extract a set of data columns to display from a
large number. And this is useful in future by jst stating
the view name instead writing the select statement every time.
