Which of the following database structures is a type of NoSQL database?

Show Suggested Answer Hide Answer
Suggested Answer: B

The database structure that is a type of NoSQL database is key-value stores. Key-value stores are databases that store and manage data as pairs of keys and values. Keys are unique identifiers that locate data in the database; values are arbitrary data that can be any type or format. Key-value stores do not use any schema or structure to organize data, but rather use hash tables or indexes to enable fast and simple access to data based on keys. Key-value stores are suitable for storing large amounts of simple or unstructured data that do not require complex queries or relationships. The other options are either different types of databases or not related to database structures at all. For example, hierarchical databases are databases that store and manage data as nodes in a tree-like structure; cloud databases are databases that are hosted and accessed over the internet using cloud computing services; object-oriented databases are databases that store and manage data as objects that have attributes and methods.Reference:CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify common database types.

B, definitely B. Key-value stores are the way to go. It's like a secret society of databases, and I'm in the know.

Hmm, I'm pretty sure it's B. Key-value stores. Unless, of course, the answer is 'all of the above' because who needs structure in this day and age?

Key-value stores, obviously! I mean, who doesn't love a good old-fashioned database with no structure whatsoever?
