Integration Services :: Incremental Loading Data In SSIS

I am looking to load data incrementally from staging to spectrum database.

Master = Staging table
Detail = Spectrum table
On below logic

.If record from Detail (Spectrum table) is null
then do insert the record into Spectrum table
set status_flag to 'A' for active
else do update the record (replace all old values with new values)
set status_flag to 'A' for active
end-if

· If record from Master (Staging table) is null
then do soft delete
set status_flag to 'D' for delete
end-if
