Answer / shalini
A table is a collection of data in the form of rows and
columns.
Whereas a View is a virtual table in which data comes from
one or more base tables and is stored as a result of a
predefined query for further use.
Uses of Views:
1.used to improve performance as they are the results of
predefined/complex queries which can be used in other
queries.
2.To provide security by granting permissions to certain
group of people only on the views rather than all the
tables database .ie. hiding sensitive data.
3.To hide complexity of data by showing only the relevant
data need to show to a user rather than confusing a uaser
by showing all the information
