The primary role of a business intelligence (BI) tool is to analyze and visualize data to facilitate informed decision-making within organizations. BI tools aggregate data from various sources, transforming it into actionable insights through reports and dashboards. This enables stakeholders to monitor key performance indicators (KPIs), identify trends, and uncover patterns that may not be apparent from raw data. By providing comprehensive analytics capabilities, BI tools empower businesses to enhance their strategies, optimize operations, and gain a competitive advantage in the marketplace.
