The information used to populate a data warehouse comes from a variety of sources. Transactional databases, spread sheets, and other administrative software are examples.
ETL (Extract, Transform, Load) Process
Data is extracted from several sources, normalised, and loaded into the data warehouse as part of the ETL process.
The warehouse is a place where data is kept in a structured, optimised, and easily accessible manner for the purposes of analysis.
