Answer / sai krishna karri

Mapplet is a reusable logic that you can use across
different mappings. Normalizer is a dynamic transformation
which converts rows to columns or vice-versa, so that is
dependendent on the input to the normalizer, it is not
fixed logic that you can reuse in other mappings.
