解説

問 67

Incorrectア
Android is indeed OSS, but it is an OS (operating system) that runs devices such as smartphones, not a DBMS. Because it does not satisfy the DBMS condition, it is incorrect.
Incorrectイ
Firefox is indeed OSS, but it is a web browser for viewing web pages, not a DBMS. Because it does not satisfy the DBMS condition, it is incorrect.
ウ
正解 The correct answer is ウ, MySQL. This question asks you to choose a product that satisfies both conditions: being OSS (Open Source Software) and being a DBMS (database management system). MySQL is a representative OSS whose source code is public and can be freely used and modified, and it is at the same time a DBMS that manages relational databases. It is widely used in the backend of web systems and is the only choice that satisfies both conditions.
Incorrectエ
Thunderbird is indeed OSS, but it is email software (an email client) for sending and receiving email, not a DBMS. Because it does not satisfy the DBMS condition, it is incorrect.

ここがポイント

OSS (Open Source Software) refers to software whose source code is public and that anyone can freely use, modify, and redistribute. Representative examples include MySQL, Firefox, Thunderbird, and Android.
A DBMS (database management system) is software that efficiently manages and operates databases. Note the distinction: among the choices, only MySQL is a DBMS, while the others are an OS, a web browser, and email software.
