Dataset
A structured collection of related data, organized so it can be queried, exported, or published as a standalone product.
A dataset is a structured collection of related records, typically organized into rows and columns (or nested JSON objects), with a defined schema describing what each field means. What separates a dataset from a raw export or scrape is structure and documentation: consistent field names, defined data types, and enough metadata that someone who didn't build it can still use it correctly.
Example
A spreadsheet of 5,000 local business names and addresses is just an export. The same file with a documented schema (field names, types, source, last-verified date) and a clear license is a dataset.
