Home -> Community -> Mailing Lists -> Oracle-L -> RE: Large databases
In OLTP systems with Large volumes of transactions, it is better to
normalize. In Data Warehouses, or systems where there is little updating or
inserting it is better to de-normalize (ie. To have all relevant data in one
table).. although in DW there are other things in play (different modeling
system altogether)
