Which term best describes the structure that stores multiple tables and the relationships among them?

• A. Database
• B. File system
• C. Array
• D. Graph

Answer: (A)

The main idea being tested is what kind of structure stores multiple tables and the relationships among them. A database is designed exactly for that: it organizes data into tables and defines how those tables relate through keys and constraints. This relational structure lets you store many tables and describe the connections between them so you can query across them efficiently. In contrast, a file system simply holds files without built-in relational links, an array is a single list of elements without multiple interrelated tables, and a graph focuses on connections between entities rather than a set of interrelated tables.
