Answer / venkatesh.layam

the first and foremost thing is sas is user friendly
in other datawarehouse there have two tools seperatly
like ETL and reporting tools
>bt in sas both are integrated sas it selt etl and any how
we are producing the reports by using different statements
in ETL is we are impoting the or extracting the data from
desperate sources thst is called extarction
transformation:we are assigning the formats and derriving
the varible from one form to another form
loading:after completed this work u are going to load the
data in libraries
so sas it self is a etl tool
when we come to reporting by using sas
by using many functions and procedures we can generate the
different types of reports

for sas there is no need to create REPOSITORY for saving.
it takes very less time to do the reports

compare to other datawarehouse languages it is occupied
less space.
