Explanation:
semi-structured data
The statement is:
" Varying fields for each entity in a JSON document is an example of ______. " Relational data # Stored in structured tables with fixed schema (e.g., SQL database). Not applicable here.
Structured data # Has a strict schema (columns and types are predefined). JSON allows variation, so not structured.
Semi-structured data # Data that does not require a fixed schema, but still uses markers (tags, keys) to separate elements. JSON and XML are classic examples. # Unstructured data # Data without schema or labeling (e.g., videos, images, free text). Not JSON.
Since JSON documents can have varying fields per entity (flexible schema), this is considered semi-structured data.
