Other software products such as Oracle, SQl take the data in
bulk and if their is no error in it they take very less time
to execute it. But if their is an error in it then it
doesn't show us the location for it and if we have 'n'
no.of records we have to check each and every one of them
but where as SAS takes each observation at a time and also
points out the location. It takes time but is accurate.
Accuracy is needed in clinical's but not the speed. And we
get accurate results.
