Answer Posted / shweta
Actually its important to use a update strategy
transofmration in the SCD's as SCDs maintain some historical
data specially type 2 dimensions. In this case we may need
to flag rows from the same target for different database
operations. Hence we have no choice but to use update
strategy as at session level this will not be possible.
