Which dataset classification includes data that is not strictly structured or semi-structured?

• A. Relational vs non-relational
• B. Structured vs semistructured vs non-structured
• C. Document vs key-value
• D. Cloud vs local

Answer: (B)

Understanding how datasets are categorized by their structure helps you know how to work with them. Structured data fits neatly into rows and columns with a defined schema, like in a relational database. Semi-structured data has some organization, such as tags or markers, but it doesn’t rely on a rigid table schema—examples include JSON or XML documents. Non-structured (unstructured) data lacks a predefined data model altogether, making it the kind of data that isn’t strictly structured or semi-structured, such as plain text, images, or multimedia. The option listing structured vs semistructured vs non-structured directly covers this full spectrum and includes data that isn’t strictly structured or semi-structured, which is why it’s the best fit. The other choices describe storage locations, database types, or storage formats rather than the way data is organized.
