Materialized Views in oracle

[Deepika Saxena]

Hi,
I know that there are two kind of views available in oracle. i.e normal views and materialized views.
normal views definition is saved in oracle engine and data is dynamically populated into the view, where as materialized views will store data just like a normal table and oracle refreshes all materialized views whenever there is a change in the parent table. i was told that the second one is not necessarily happen. please correct me if i am wrong.

Thanks.

You are correct. I believe it's an option on the materialized review whether you want it to refresh automatically.
