Data warehouse

A data warehouse is a centralized repository designed to store, manage, and analyze large volumes of data from various sources. It organizes data in a structured manner, enabling businesses to derive insights and make informed decisions. Unlike operational databases, which focus on day-to-day transactions, a data warehouse is optimized for query and analysis, supporting decision-making processes. Key features include subject orientation, integration of heterogeneous data sources, and time-variant storage, ensuring that data remains consistent and reliable. By utilizing a data warehouse, organizations can streamline their data analysis efforts and enhance overall operational efficiency.
