A data warehouse is a type of data management system that is designed to enable and support business intelligence (BI) activities, especially analytics. Data warehouses are solely intended to perform queries and analysis and often contain large amounts of historical data.

A data warehouse is a centralized repository of historical, integrated, and organized data collected from multiple sources. It is designed to support business intelligence and analytical reporting by providing a comprehensive view of data for analysis and decision-making. Data is extracted, transformed, and loaded into the data warehouse, ensuring consistency and quality. It allows users to analyze trends, patterns, and relationships in data over time.
