Answer Posted / medatati satya teja ravi kiran
UNION:1)we can create multiple input groups,but only one
out put group
2)we can connect heterogeneous sources to a union
transformation
3)The union tf does not remove duplicate rows.To remove
duplicte rows, we must add another tf such as router or
filter tf
JOIN:1)Used to join source data from two related
hetorogeneous sources residing in different locations or we
can join data from the same source
2)The joiner tf remove duplicate rows...
