what is incremental data aggregation?

Answer Posted / suraj kedia

Incremental aggregation means applying only the captured
changes in the source to aggregate calculations in a session.
When the source changes only incrementally and if we can
capture those changes,then we can configure the session to
process only those changes.This allows informatica server to
update target table incrementally,rather than forcing it to
process the entire source and recalculate the same
calculations each time you run the session.By doing this
obviously the session performance increases.
