A traditional database analyzes one region of a database at time. An NCR Teradata data warehouse is designed for parallel processing, dividing the database into chunks. The warehouse is also expandable without a degradation of system performances. To the bottom line, data warehousing means higher revenues and cost reduction. The technology allows businesses to grow and identify new customers by knowing the needs and wants of an individual with a particular customer profile.
Firms can improve financial reporting, comparing records of goods sold with the bottom line.
Big businesses can also determine which clients are profitable in terms of post-sale service costs and refunds. When a cashier scans a product at the check-out line, a replacement is on the truck with the next delivery. One challenge in the class is a lack of resources. Hoffer co-authored one of the few texts with a chapter devoted strictly to data warehousing. He is using the chapter from his Modern Database Management , written with Fred R. McFadden and Mary B. Prescott, as one of the required class readings.
