View:view is a logical table,it don't have own data,the
query which we mentioned after the create view statement
will be compiled and stored in server as a database
object.once we call the view,the compiled query will be
fetch the data from master table.
The DML operations will be reflected in master table or
view suddenly.
Materialized view:The Materialized view required physical
memory space.it will be created from target master
table,which located in some other location.A materialized
view can be created either single mater table or multimater
tables from multiple master sites.the changes which we have
done in master table will reflect in particular interval
time.the materialized view,which created from multiple
master tables,will updated its individual batch files....
