data obtained directly using methods such as a survey or an experiment.
Data from primary research - that is, research on specific individuals, from a survey or other database. Much the same as raw data. Contrasts with secondary data.
primary data refers to data in its virgin state; as introduced to the system from an external source (such as a person or department). "Source" defines who is responsible for entering the data to a system, and who has ultimate authority for the definition of the data element. (See Generated Data).
