What are the differences between data, a dataset, and a database?
Data are observations or measurements (unprocessed or processed) represented as text, numbers, or multimedia. A dataset is a structured collection of data generally associated with a unique body of work. A database is an organized collection of data stored as multiple datasets, that are generally stored and accessed electronically from a computer system that allows the data to be easily accessed, manipulated, and updated.
