10 Discoverer

This chapter describes Oracle Discoverer metrics.

Discoverer

Oracle Business Intelligence Discoverer is a business intelligence tool for analyzing data. Discoverer provides an integrated business intelligence solution comprising a set of intuitive ad-hoc query, reporting, analysis, and Web-publishing tools. These tools enable nontechnical users to gain immediate access to information from data marts, data warehouses, and online transaction processing systems. Discoverer integrates seamlessly with Oracle Portal, enabling rapid deployment of Discoverer workbooks and worksheets to Web portals.
