MYSQL은 데이터베이스 소프트웨어입니다. 일반적으로 데이터를 추가하거나 검색, 추출하는 기능을 모두 포함해서 데이터 베이스라고 부릅니다.

MYSQL은 세계에서 가장 많이 쓰이는 오픈 소스의 관계형 데이터베이스 관리시스템(RDBMS) 입니다. MYSQL은 PHP 스크립트 언어와 상호 연동이 잘 되면서 오픈소스로 개발된 무료 프로그램 입니다. 그래서 홈페이지나 쇼핑몰(워드프레스, 카페24, 제로보드, 그누보드)등 일반적으로 웹 개발에 널리 사용하고 있습니다.

MAMP란 웹사이트를 개발할 때 쓰이는 기술 스택인 macOS, Apache, MYSQL, PHP의 약어이자 솔루션 스택이다.
