We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.

Our company has a well designed database having several hundred tables. It has been refined over years to offer incredible efficiency and performance. It is remarkably consistent in making convention and use of appropriate types. It is not unusual, except in its consistency and elegance; nothing fancy or tricky, just solid, careful design. We interview hundreds of engineers having usually CS or Masters degrees, and many senior engineers with years of experience. We interview extremely smart people. Yet a very small number of candidates are able to successfully implement the basic SQL needed to query several tables. It's not because the sample is too hard, or because the candidates are dumb. It's because SQL is hard -- not the syntax, in particular, but, like C it's a very terse and compact language used to express more than a few, indeed arguably most or all, data relationships. I "learned C in a day" after reading the book. I learned SQL in several days. But understanding how to write software, and manipulate data well is my life's work. In my 50s now, having lead many engineering organizations and written much software, I have come to see that those having great hubris, disdain and impatience are typically blind to their own ignorance (often correlated with truly brilliant, yet utterly ineffective developers). Those humble (humbled?) enough learn how to use the abstrations that minds more brilliant have created are invariably the best engineers. Using their abstractions mindfully has helped me understand that SQL I learned in a day back in 1985 quite a bit better in the intervening decades.
