**Data Warehousing**

Data warehousing refers to the process of collecting, storing, and managing large volumes of data from multiple sources in a centralized repository. This repository, known as a data warehouse, is designed to support business intelligence activities, including reporting, analysis, and decision-making. Data warehousing enables organizations to consolidate disparate data, ensure data quality and consistency, and perform complex queries efficiently. It plays a critical role in turning raw data into actionable insights that drive strategic planning and operational improvements.
