Step-by-step explanation:
In the context of a database, end-user data consists primarily of raw facts of interest to the end user. This includes information collected through in-depth interviews, focus groups, and analysis of content sources, or it could be quantitative data such as numbers and statistics. For example, if someone is conducting a study on housing prices, the raw data could be a collection of sale prices for homes in the area.
