Over the past three decades, computers have taken over the world. Twenty-five years ago, we lived analog. We communicated using an analog POTS telephone, we tuned in to analog FM radio stations, and we went to the library and browsed the stacks for information. Buildings were constructed using hand-drawn blueprints; graphic artists worked with pen, brush, and ink; musicians plucked strings and blew into horns and recorded on analog tape; and airplanes were controlled by physical cables connecting the yoke to the control surfaces.
But now everything is computerized and digital. Consequently, every member of society needs to be familiar with computers. That does not mean having the deep knowledge of a techie, but just as poets need to study a little math and physics, and just as mathematicians need to read a little poetry, so too does everybody today need to know something about computers.
I think that this book really helps to address the knowledge gap between techies and laypeople, by providing an accessible and easy-to-read discussion of SQL—a core database technology.
