how can we update without using update transformation.
wt is push down operation in informatica.
which lookup gives more tuning performance. if so why.

Answer Posted / ashwin

We can use update override in the target table in mapping.

Push Down Optimization is an optimizing technique in
informatica 8. Integration service pushes the transformation
logic either to the source database or to the target
database rather than executing the logic by itself.

I think dynamic lookup gives a better performance since it
allows us to tune the cache sizes(index and data).
