Business intelligence (BI) gives organizations the ability to strike gold in the mountain of information they have. IT departments can use BI to accumulate and aggregate operational data into data warehouses and to pull rich information from that data store. OLAP and data-mining technologies let organizations query, group, and analyze this information in ways that relational data-access techniques can't achieve. And reporting technologies let IT professionals deliver crucial business information to decision makers in formats they can use.

Best Data-Mining Tool. SAS Enterprise Miner lets users mine their data by providing multiple interfaces, scalable processing, sampling, data partitioning, transformations, and filtering. The tool also offers data replacement, descriptive statistics, graphs and visualizations, clustering, market-basket analysis, and Web-path analysis. Readers who voted for Enterprise Miner appreciated its model-comparison and drill-down capabilities.

Best Data-Warehousing Tool. BusinessObjects Enterprise 6.0 is a data-warehousing tool that lets you easily maintain and export data to and from multiple systems.

Readers praised BusinessObjects Enterprise—which delivers end-user data access, advanced analysis, customized interfaces, and administrative services for security and auditing—as an "all-in-one" solution.

Best ETL Tool. BusinessObjects Data Integrator 6.5 is an extraction, transformation, and loading (ETL) tool that lets you design, test, debug, edit, maintain, run, and monitor data-integration jobs.

Best OLAP Tool. Cognos PowerPlay lets you perform multidimensional analysis and create and share reports across your organization.
