One thing that I would find cool as a follow-up to this article would be something like a decision tree (I understand it would get very complicated, very fast, but it should be fun): I, as a developer, am using AWS/Azure and I need features X,Y,Z, tell me which database I should pick.<p>Probably even better if it were a model trained extensively on the documentation / features of each individual database and it would also give references to the answer (see how Bing does it).
