Quizplus · Accepted Answer

A data warehouse is a separate database used for analysis and reporting rather than transaction processing. It typically stores historical data from multiple sources, cleans and transforms the data, and structures it for efficient querying and analysis. It is designed to support complex analysis and reporting, rather than fast updates or transaction processing, which are better handled by traditional transaction processing databases. Hard copies of transaction processing records are not typically stored in a data warehouse, and it does not replace traditional transaction processing databases. While a data warehouse may facilitate faster analysis and reporting, it does not generally speed up transaction processing.
