Incremental aggregation is nothing but a method of maintaing
new records in the target when we use an aggregator in our
mapping..
With incremental aggregation only those records which are
new in the source are processed in the mapping excluding
those which have been processed.
The data which was earlier present in the source n has been
processed is stored in the cache and the new records are
processed along with them.
For this we need to select the option INCREMENTAL
AGGREGATION from session properties.
