2. Explain why it is important for an airline to use a real-time data warehouse.

As business intelligence (BI) becomes a critical component of daily operations, real-time data warehouses that provide end users with rapid updates and alerts generated from transactional systems are increasingly being deployed. Real-time data warehousing and BI, supporting its aggressive Go Forward business plan, have helped Continental Airlines alter its industry status from “worst to first”
and then from “first to favorite.” Continental Airlines is a leader in real-time BI. In 2004, Continental won the Data Warehousing Institute’s Best Practices and Leadership Award.
