Dual Systems/fallback/replication? - response (1) by dnoeth

Hi Nishant,
"Fallback" is definitely wrong, this is just protection from hardware failure.
Of course "Journal Tables" might be used to rollback from a wrong load, but this is not specific for this scenario.
"replicated" might indicate "Dual Systems", but this still doesn't mean "dedicated to the load" becuase both systems need to be loaded.
"user view access switching" seems to be the only correct one, create a copy of the data, load and then replace the access view from old to new.
 
This Q seems to be from CertificationPath, i just clicked on a few other questions and two had definitely wrong answers :-(
