Indeed, and the article title doesn't mention C++, not clear why it's in the submission.
Furthermore, the whole piece seems to be just a different (data oriented, I guess) view at class design patterns because 'this approach is more known to data professionals'. Sounds like reinventing the wheel/not invented here approach, and I'd prefer that people who code, even if they're data professionals, will just get familiar with the source (e.g. Design Patterns by the gang of four)
