ITPEC IP April 2020 Question 22

MySQL — an open-source relational database management system.

MySQL stores data in tables that are defined, queried and updated with SQL, and its Community Edition is released under the GPL. It is widely used as the database behind websites, often together with Linux, Apache and PHP (the LAMP stack). PostgreSQL is another well-known open-source DBMS.

Answer (c)

Why not others:

• •(a) Android — an open-source operating system for smartphones and tablets, based on the Linux kernel
• •(b) Firefox — an open-source web browser from Mozilla
• •(d) Thunderbird — an open-source e-mail client, also from Mozilla

Key rule: All four options are OSS, so the question is what each product does: Linux and Android are operating systems, Firefox a browser, Thunderbird a mail client, Apache a web server, LibreOffice an office suite, and MySQL and PostgreSQL are DBMSs.
