Yes...suppose you have a mapping in that you have source 1 then expression transformation then the target..then this sequence will be called a pipeline and source will be the upstream transformation and target will be downstream transformation for that expression transformation .

Say a Transformation1 accepts input from transformation 2 and passes the output to a transformation 3 , then

transformation 2 is called an upstream transformation.
transformation 3 is called a downstream transformation.
