Hi Kpk

I Think u r answer correct in Oracle view but question is
how can we use the materilized views in dataStage.

My view is No need of materialized view in DataStage it can
be used in Reporting time ( in OLAP)

Materilized views are similar to normal views, but the
difference is, materilized views are stored in the databse
and they are refereshed timely to get the new data....
