This profiling method works only with schemas. And a single schema may, by definition, correspond to a number of heterogeneous phenomena. Imagine that you see a shadow resembling a huge dog. If you have access only to the shadow, how can you tell with certainty what object created it? It may simply have been made by an arrangement of someone’s hands as part of a shadow play.
