structured data
Schema-bound digital records
Structured data is information organized in a predictable, standardized format—typically rows and columns, fields and values, or tagged categories that computers can easily parse and query.
Database tables, spreadsheets, and XML files contain structured data.
The term usually appears in contrast to unstructured data like free-form text, images, or video, which lack consistent internal organization.
