Quizplus · Accepted Answer

A data warehouse is a specialized database designed for storing and analyzing large volumes of data. It is used to aggregate data from various sources, such as operational systems, and to transform and clean that data so that it can be used by business intelligence tools to generate reports, dashboards, and other data visualizations. A data warehouse typically employs techniques such as ETL (extract, transform, load) to move data from source systems into the warehouse, and may also use data modeling and indexing to optimize query performance.
