By the end of on average day in the early 21st century, human beings searching the Internet will amass eight trillion gigabytes of data. This staggering amount of information - unprecedented in history - can tell us a great deal about who we are - the fears, desires, and behaviors that drive us, and the conscious and unconscious decisions we make. From the profound to the mundane, we can gain astonishing knowledge about the human psyche that less than 20 years ago seemed unfathomable.

SQL, pronounced ess-que-el, is a domain-specific language; this means that it is made for a certain purpose. Unlike general purpose languages like C++ or Ruby, SQL was made for a singular purpose, and to be excellent at that one purpose. It’s similar to the way HTML is designed to make web pages, and it falls into the same niche as much soft code. While alternatives to SQL like ISAM or VSAM exist, they have largely faded out of use due to SQL’s superiority. SQL is the pioneer of accessing N records with a singular command, and generally works without indexing.
