Answer Posted / shashikiran

If it is horizontal join then we should use joiner transformation having common columns in both the flat files if it is more than 3 flat files, then number of joiners will no. of flat files - 1 i.e,
if suppose there are 4 flat files then 3 joiners are used.
If the flat files structure is same then we can go for vertical joining by using Union transformation or by using indirect file loading concept.
