PPI or NUSI? - response (3) by dnoeth

Hi Nishant,

access with partitioned column alone (with out PI) will not be that much efficient as it would have been with PI + partioned column.. agree?

No. When only the partitioning column is used the performance is exacty the same regardless if the partitioning column is also part of the PI or not.
There's a lot of details about PPI in the "Database Design" manual,  Chapter 9: Primary Indexes and NoPI Objects
