Quizplus · Accepted Answer

A data warehouse is a large, corporate-wide database that integrates data from various sources within an organization, such as billing, accounting, order fulfillment, distribution, customer service, marketing, and sales. It is designed to support business intelligence activities such as data mining, online analytical processing (OLAP), and decision making. Data marts, customer information systems, decision support systems, and data clusters are all related concepts, but they do not necessarily have the same scope and purpose as a data warehouse.
