Refer to the mapping illustrated below. Assume that the mapplet definition is valid and that the individual transformation expressions are valid. Select the statement that is correct.
Choose Answer
(A)
The mapping will be valid as it is.
(B)
The mapping is valid because the third mapplet output group, Update Changes, does not have any output ports connected to a transformation or Target definition.
(C)
The mapping is invalid because you cannot concatenate two or more data flow paths together into one mapplet input group.
(D)
The mapplet is invalid because the number of output ports in each output group does not match.

I just found this blog and I didn't realize that the topic of ETL had so much detail. I've been helping a friend start a dotcom site for data integrations. Seeing how much expertise you have in this area, perhaps you could read through his site and see how well it stacks up?
