The outlook for corporate spending on business intelligence tools looks bright, but companies aren’t necessarily going to commit large resources to the latest software upgrades and new applications hitting the market. Instead, according to a new market perspective and forecast from The Data Warehousing Institute, companies will focus their spending "on bread-and-butter issues" and build on their existing data warehousing program, particularly hub-and- spoke architectures. "Despite the economic slowdown, the business intelligence market will march ahead," says the 2002 Data Warehousing and Business Intelligence Perspectives TDWI Report.

"Companies will use the slowdown to focus on implementing what they already have or reevaluating their enterprise architectures." Over time many companies with an established data warehousing and business intelligence platform have developed a hub-and-spoke architecture with a core data warehouse linked to multiple data marts. In a recent survey of 173 companies, the TDWI reported that 56 percent used a hub- and-spoke architecture, compared with 22 percent who had only a data warehouse, 14 percent with independent data marts, six percent with federated data marts and two percent with virtual data warehouses. "Companies frequently evolve to a hub-and-spoke architecture despite how they started building their intelligence infrastructure," the TDWI report says. "In addition they have deployed Web-based analysis tools and portals to facilitate universal access and self-service query/reporting."

In the future, companies will also begin taking advantage of SOAP, UDDI and other Internet protocols to better Web enable their business intelligence programs."
