Two examples of primary data are survey responses collected directly from individuals and experiments conducted to gather specific data. Two examples of secondary data are data obtained from government reports and data collected from previous research studies.
A secondary primary source is a document or source that is created based on primary sources. It provides analysis, interpretation, or commentary on primary sources rather than direct information or data. Examples include textbooks, scholarly articles, or documentaries that discuss or analyze primary sources.
Primary data is data collected firsthand, through surveys, interviews, experiments, etc. by the researcher, while secondary data is existing data that has already been collected by someone else. An example of primary data would be survey responses collected by a marketing team for a new product. An example of secondary data would be industry reports or census data obtained from a government website.

Data consistency constraints are rules that define the allowable values and relationships within a database to ensure that the data remains accurate and reliable. These constraints help maintain the quality and integrity of the data by preventing conflicting or incorrect information from being stored. Examples include primary key constraints, foreign key constraints, and unique constraints.
