Extraction Job which one is faster?
Posted: Fri Jun 23, 2006 3:15 am
Hi all,
I am extracting aggregated data from the warehouse using oracle sql ( invovled joining dimension and fact tables , summing up some measures, some translation of data column and sorting )
Now i need to build the DS job for it.
-should i get better performance if I break the logic down into a series of stages ( like ext, join, xfm, aggre, sort...etc )?
-Or let the Oracle handle all the processing? ( I am pulling data from one source only )
Thanks and Regards,
william
