A kingdom of concerns

When doing object-oriented programming and following SOLID principles, there is sometimes a concern that classes will proliferate and you end up with a Kingdom of Nouns.

I find it more concerning when there is a proliferation of concepts. Too many layers, too many patterns, too many frameworks. The best designs I’ve seen provide just one or two concepts that manage to tie everything together without breaking orthogonality.

The great thing about Rails and Sinatra was that they boiled previously conceptually heavy domains down to a simpler, better set of ideas. In doing so, they move you up the hierarchy of needs, so to speak, and you still end up inventing your own concepts and nouns. More on that soon!
