SQL stands for Structured Query Language. It is the standard programming language used to communicate with and manage data in relational databases. It's used for tasks like retrieving data, updating records, creating tables, and setting permissions.

A relational database is a type of database that stores and provides access to data points that are related to one another. Data is organized into tables consisting of columns and rows, similar to a spreadsheet. MySQL, SQL Server, and PostgreSQL are all examples of relational databases.

As a database grows, a poorly written query can become extremely slow, causing the entire application to feel sluggish or even time out. Query optimization is the process of rewriting queries and creating database indexes to ensure that data can be retrieved in milliseconds, even from tables with billions of rows.

SQL is the language you use to talk to a database. MySQL is an actual Database Management System (DBMS)—a specific software program that stores the data and understands the SQL language. Think of SQL as the grammar and vocabulary, and MySQL as a person who understands that language.

SQL commands are generally grouped into categories. The main ones are DDL (Data Definition Language) for defining structure (e.g., CREATE TABLE), DML (Data Manipulation Language) for managing data (e.g., INSERT, UPDATE), and DCL (Data Control Language) for managing permissions (e.g., GRANT).
