If I were going to do this, I would think about separate subclasses for 
raw data, normalized data, and segmented data.  If you think about 
methods for each class, you will probably want them to behave 
differently based on whether they are operating on raw, normalized, or 
segmented data.  Having separate subclasses makes this pretty 
straightforward.  Just a thought, though.
