DA0-002 Data Concepts and Environments Practice Question
A company stores customer data in a relational database with tables for orders, products, and customers. Which type of data best describes this?
⚠ Common exam trap
CompTIA often tests the misconception that any data stored in a database is automatically structured, but the trap here is that candidates might confuse semi-structured data (like JSON in NoSQL) with relational tables, which are strictly structured.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Structured data
A is correct because the data is stored in a relational database with predefined schemas (tables for orders, products, and customers), which enforces a fixed structure of rows and columns. This makes it structured data, as each field has a specific data type and relationships are defined via foreign keys, enabling efficient querying with SQL.
