A datawarehouse is a centralized repository of integrated and historical data from various sources within an organization. It is designed to support business intelligence and analytics by providing a single source of truth for data analysis and decision-making. Unlike traditional databases, a datawarehouse is optimized for querying and reporting, allowing for complex data analysis and trend identification. It acts as a foundation for data-driven decision-making, providing a comprehensive and holistic view of an organization’s data. Datawarehouses are essential for businesses to gain insights, make informed decisions, and stay ahead in today’s data-driven world.
