Sherlock Holmes was a Data Engineer or How SQL changes the way one thinks

Here is an idea – SQL solutions usually rely on deduction, programming – on induction.

Based on anecdotal evidence, there are differences between approaches used by data oriented and code oriented practitioners. Supposedly, tools we use affect our reasoning process. Naturally, “When one has a hammer…”

It looks like writing SQL and solving problems with existing data exercises deductive reasoning. Designing new software and coding it – uses inductive reasoning.

This is why – when solving data problems – SDEs  jump to  binary trees, but DEs create relational tables first.

Of course, this dichotomy comes with the usual disclaimer:

“All generalizations are dangerous, even this one.”

Alexandre Dumas
