A media company is cataloguing its data assets. Which asset below counts as unstructured data?
Show answer and explanation
Answer: A
Photographs have no predefined schema or labelled fields that a query engine can filter on, so they are unstructured data. Relational tables are structured, while YAML manifests and JSON events carry keys and nesting that describe their content, which makes them semi-structured.
Why the other options are wrong
- B. Invoice line items sit in typed columns under a fixed schema, which makes them structured rather than unstructured data.
- C. A YAML manifest labels each value with a key and uses nesting, so it is semi-structured, not free-form unstructured content.
- D. A JSON event describes its fields with property names and hierarchy, so it is semi-structured rather than unstructured.
