Although data warehousing has been around for more than a decade, the warehouse of tomorrow will bear little resemblance to the programs in place today. In fact, according to a white paper being circulated at The Data Warehousing Institute World Conference Winter 2002 in New Orleans from Knightsbridge Solutions, data warehouses will shift from a corporate cost center to a program that generates significant revenue, particularly as businesses look for better ways to attract and retain customers.
"Money is tight and the business case for the data warehouse is a lot higher," says Mike Amble, Knightsbridge practice area leader for telecommunications. "Businesses want a better data warehousing return on investment they want the warehouse used for better analysis of risk management and marketing automation." According to Knightsbridge: the top trends affecting data warehousing include:
- Data Hubs Versus Relational Databases. In an effort to control costs and improve performance, enterprises are increasingly implementing data hubs in their data warehouses instead of using relational databases.
- Active Data Warehouses. As enterprises face competitive pressure to increase the speed of decision making, the data warehouse must evolve to support real-time analysis and action.
- Integrated Customer View. Obtaining a 360-degree view of the customer is the single most popular rationale for large-scale data warehousing efforts.
- Exploding Data Volume. The amount of usable data in the average data warehouse will increase almost 300 percent to more than 1.2 terabytes in 2002. Escalating end-user demands also play a part as organizations collect more information and store it for longer periods.
