SQL

SQL is the most used language for interacting with databases. It stands for Structured Query Language, and does exactly what it promises: allow you to write well-structured programs for your databases. With those databases you could start a blog, a web shop, an online game, a website that allows users to create accounts, and much more!

Prerequisites: A tiny bit of (server-side) programming knowledge could be useful.
