Which of the following describes an Enterprise Data Warehouse (EDW)?

An Enterprise Data Warehouse (EDW) functions as a centralized repository for business information, collecting and consolidating data from multiple sources across an organization. This integration allows for more efficient reporting, analysis, and decision-making by providing a comprehensive view of the company's data.

By centralizing data, the EDW facilitates consistent reporting and data governance, making it easier for different business units to access reliable and timely information. This architecture supports complex queries and advanced analytics, enabling organizations to derive insights that drive strategic initiatives.

The other options do not accurately capture the essence of an EDW. A single-source database for a specific application refers to a narrower scope and does not encompass the broad, cross-functional data integration of an EDW. Temporary storage for data backups implies a short-term solution rather than a strategic approach to managing enterprise data. A decentralized system for managing transactions contradicts the fundamental concept of an EDW, which is designed to centralize and streamline data storage and access across an organization.
