FC0-U71 Practice Question: A user needs to store customer information…
A user needs to store customer information including name, address, and order history. Which database type is most appropriate?
⚠ Common exam trap
Watch out — candidates often choose NoSQL databases (Option C) because they assume 'order history' implies large-scale or flexible data, but the question specifies structured customer information with clear relationships, making relational databases the correct fit for ACID-compliant transactional integrity.

Correct answer & explanation
✓
Relational database
A relational database is the most appropriate choice because it organizes data into tables with rows and columns, allowing efficient storage and retrieval of structured customer information (name, address) while supporting relationships to order history via foreign keys. This structure enables ACID compliance and complex queries using SQL, which is ideal for transactional data with clear schema requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Hierarchical database
Why it's wrong here
Hierarchical databases organize data in a tree structure, which is inflexible and not suitable for many-to-many relationships.
- ✗
Flat-file database
Why it's wrong here
Flat-file databases store data in a single table, leading to redundancy and difficulty in querying related data.
- ✗
NoSQL database
Why it's wrong here
NoSQL databases are designed for unstructured or semi-structured data, not ideal for structured relational data like customer orders.
- ✓
Relational database
Why this is correct
Relational databases use tables, keys, and relationships to efficiently store and query structured data like customer info and orders.
