Which is structured data?
Why B is the answer
A table of orders with fixed columns
Structured data follows a fixed schema. The others are unstructured.
In detail
- Fixed columns make a table structured data.
- Emails and photos have no fixed schema.
Use case
An illustrative scenario, not a real incident.
An order table has the same columns on each row, so it is easy to sum and filter.
