What is also known as Data Warehouse?

• A. MARS- Mission Analysis and Reporting System
• B. Data Warehouse System
• C. Knowledge Repository
• D. Archive System

Answer: (A)

A data warehouse is a centralized repository that collects and stores integrated data from multiple sources to support reporting and analysis. It emphasizes historical data, consistency, and subject-oriented organization to enable fast queries and business intelligence across the organization. This setup is commonly referred to as a data warehouse system, the infrastructure that houses the data, the processes to extract, transform, and load it, and the tools used to access it. The other terms describe different concepts: a knowledge repository focuses on capturing and sharing knowledge assets rather than structured data for BI; an archive system is for long-term retention with less emphasis on analysis; and a specific application name like MARS refers to a particular system rather than the general term for the data warehouse concept.
