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.

I know non-relational databases don't store data in tables like relational ones, so D should be ruled out for sure.

I feel like non-relational databases are great for flexibility, but I can't recall if they really excel in transaction accuracy like relational ones do.

I remember practicing a question where non-relational databases were described as not using SQL, so I think option B is definitely incorrect.

I'm pretty confident A is the right answer. Non-relational databases are optimized to handle large, unstructured datasets, which is a key advantage over traditional relational databases.

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.

Hmm, I'm a bit confused on this one. I know non-relational databases don't use the SQL language, but I'm not sure if that's the key characteristic. I'll have to think this through carefully.
