[All WGU Data Management - Foundations Questions]

Which characteristic is true for non-relational databases?

AThey are optimized for big data.

BThey support the SQL query language.

CThey are ideal for databases that require an accurate record of transactions.

DThey store data in tables, columns, and rows, similar to a spreadsheet.

Show Suggested Answer

Suggested Answer: A

Non-relational databases (also called NoSQL databases) are designed for handling big data and unstructured data efficiently. They are optimized for horizontal scaling, making them ideal for large-scale distributed systems.

Option A (Correct): Non-relational databases are optimized for big data, handling massive volumes of data across distributed architectures.

Option B (Incorrect): NoSQL databases do not use SQL as their primary query language. They often use JSON-based queries (e.g., MongoDB).

Option C (Incorrect): Transaction-heavy applications require ACID compliance, which relational databases (SQL) handle better than NoSQL databases.

Option D (Incorrect): NoSQL databases use document, key-value, graph, or column-family storage models, not tables, columns, and rows like relational databases.

D is definitely wrong. They don't use tables like relational ones.

Okay, I've got a strategy here. Non-relational databases are often called "NoSQL" databases, so they likely don't use the traditional table-based structure like a SQL database. I'm going with A.
