Answer Posted / mkumar.it
Snapshots and Materialized view are used interchangibly as
both are almost same. However, materialized view is having
additional feature of query rewrite which is not in snapsot.
In this feature, suppose you made any materialized view
using some aggrigate function and you query base table from
sql using same aggrigate funtion, the query will execute on
the materialized view instead of querying base table
provided you have query rewrite priviledge.
