Answer / mike
Well an aggregator transformation is an active connected
transformation which is used to convert detailed values in
to summary values by using aggregator functions like sum,
avg, max, min etc...if a mapping contains aggregator
transformation the informatica server executes the
expression each for every group of record. The aggregator
transformation is based on four parameters
1)groupby ports
2)group expression
3)stored inputs
4)incremental aggregation
As every one knows an aggregator transformation is active
because it executes less out put than no of inputs(detailed
values in to summarized values)...
By the definition an active transformation is the
transformation in which the no of outputs will be less than
inputs...
by the definition an passive transformation is the
transformation in which the no of outputs equals to the no
of inputs...
corect me if i was wrong....
