Which of the following is an example of unstructured data?
- AA relational table linking orders to customers by key values.
- BA JSON document whose fields differ from one record to the next.
- CA spreadsheet of rows and columns with consistent headers.
- DA collection of audio and video files with no fixed schema. Correct
Audio, video, documents and images are unstructured data because they carry no fixed or partial schema. Unstructured data is data that is not structured or semi-structured, and the grounding lists audio and video files among its examples.
Why A is wrong: Tempting because it is a clear data example, but tables related by key values are structured data following a fixed tabular schema.
Why B is wrong: Tempting as JSON looks free-form, but JSON with varying fields is the common format for semi-structured data, not unstructured data.
Why C is wrong: Tempting because spreadsheets feel informal, but rows and columns with consistent headers form a fixed schema, making this structured data.
Why D is correct: Correct. Unstructured data is data that is not structured or semi-structured, and the grounding lists audio and video files among its examples.
