# Notes, Code, and Experiments with SQL

## Quick Overview

- SQL: **S**tructured **Q**uery **L**anguage

- Programming language designed for manipulating relational databases

## Motivations for Mastering SQL

I have used SQL in several projects, such as Resumenes.org, YouShare.TV and [BitcoinArgy.com](https://bitcoinargy.com), specifically with MySQL and SQLite. Now, I'm engaging in a systematic exploration to learn more techniques for optimizing my programs and to incorporate **PostgreSQL** into my skill set.
