Data warehouse

Data-warehouse

A data warehouse is a centralized repository designed to store and manage large volumes of data from various sources, enabling efficient analysis and business intelligence applications. It serves as a decision support system, allowing organizations to consolidate data from disparate sources into a unified schema. This structured environment facilitates data analysis, reporting, and strategic decision-making. Key features of a data warehouse include its subject-oriented nature, integration of heterogeneous data sources, and time-variant storage, which collectively support management’s decision-making processes. By providing a single source of truth, data warehouses empower organizations to derive insights and make informed decisions.
