A data warehouse is an organization’s centralized repository of integrated data from one or more disparate sources. It stores current and historical data in one single place that are used for creating analytical reports for knowledge workers throughout the enterprise. A data warehouse is designed to store and manage large amounts of operational and transactional data, enabling business users to make data-driven decisions quickly and efficiently. By using a data warehouse, companies can access all their business intelligence in one central location, making it easier to identify trends, assess performance, and formulate strategies. Additionally, storing data in a data warehouse improves data quality and provides organizations with more meaningful insights into their operations.
