A View is a data base object also called as virtual table
which is created on a select statement.
A view can be created using multiple tables.
A view is stored in a temporary memory.
An index is also a DB Object which is used to increase
query performance and index is created based on columns of
a table.
An index is created on multiple columns but on a single
table.
Index is maintained by Oracle Server itself.
