It sounds like you want a new class X that does three things: knows where the data is and how to access it, knows how the data are to be processed and can do this when asked, is able to provide a "results" object when requested. The results object can store who made it and with what processing module, thus indirectly linking to the data and techniques (which the X instance may or may not store, as is convenient).
