Answer / murali krishna

Transformations can be active or passive.

- An active transformation can change the number of rows
that pass through it, such as a Filter transformation that
removes rows that do not meet the filter condition.

- A passive transformation does not change the number of
rows that pass through it, such as an Expression
transformation that performs a calculation on data and
passes all rows through the transformation.

Answer / saradhi

Active Transformation means the no of records u got from
source table is filtred by the transformation and got only
few records may or may not at the target table so this an
active transforamtion. example: if u filtered the data by
agreegate function like sum(sal) here u got only one column
as output so its an active.
Passive means the no of records u got from source table is
equal to the target table records even though the
transforamtion is done
example: sal+comm here u got same no of records as source
after filtering also.

Answer / soujanya

if all source records sends to target or for further
processing using any tranformation then the output is same
as source no. of records then it is passive transformation.
otherwise it is active

source no of records = target no. of records(passive)

source no. of records!=target no. of records(active)
