MySQL introduction

Part of LAMP. One of the most rowerful SQL servers out there is called MySQL and surprisingly enough, its free. Yes, free. I now use this instead of MS Access, Filemaker or FoxPro (lol). However, since Oracle is now the owner of MySQL there is a fork of MySQL called MariaDB which want to keep the project as open as possible. I am thinking about switching to MariaDB because it has more features compared to MySQL which saw little improvements. The commands or Mariadb and MySQL are about the 'same'. You can manage MySQL or Mariadb with good ol phpmyadmin or adminer

For NoSQL db, look at MongoDB.
