Why we need datasets ratherthan sequential files?

Answer Posted / sagar

When you use sequential file as Source,at the time of
compilation it will convert to native format from
ASCII.where as,when you go for using datasets... conversion
is not required.Also, by default sequenctila files we be
processed in sequenc only.sequential files can accommodate
up to 2GB only.sequentila files does not support NULL
values....all the above can me overcome using dataset
stage....but selection is depeneds on the
requirement....suppose if you want to capture rejected
data....in that case you need to use sequential file or
fileset stage....
