Explanation of Data Warehouse

A data warehouse is a centralized repository that stores large volumes of structured data from multiple sources. It is designed to support business intelligence, analytics, and reporting by providing a unified and consistent view of the data. Data warehouses use ETL (Extract, Transform, Load) processes to integrate data from various systems, ensuring data quality and consistency. They enable complex queries and analysis, allowing businesses to gain insights and make data-driven decisions. Data warehouses are essential for organizations that need to consolidate and analyze large datasets. Effective data warehouse management involves proper data modeling, governance, and maintenance practices.
