Data warehouses are essential to helping businesses make data-driven decisions, gain knowledge from both old and new data, and support a variety of company processes, including sales, marketing, finance, and operations.
Organizations frequently develop data marts, which are subsets of the data warehouse customized for particular departments or business units, in addition to the primary data warehouse.
The acronym "EDW" stands for "Enterprise Data Warehouse." Designed to provide business intelligence (BI), reporting, and analytics throughout the whole firm, an enterprise data warehouse is a consolidated and comprehensive collection of an organization's data. The ability to consolidate, integrate, and manage data from diverse sources for analysis and decision-making is provided by it, which acts as a single source of truth for data.
