Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Key-Value
Why it's wrong here
Key-value stores are simple and lack the querying power required for document structures.
✗
Relational (RDBMS)
Why it's wrong here
Relational databases require a predefined schema and are less flexible for semi-structured data.
✓
Document-oriented
Why this is correct
Document databases support flexible schemas, making them ideal for JSON-like data.
✗
Graph
Why it's wrong here
Graph databases are for managing complex relationships, not for storing semi-structured documents.
