What Is Business Intelligence (BI)? Types, Benefits, and Examples

Business Intelligence refers to the technologies, processes, and tools that collect, analyze, and present data to support decision-making. At its core, BI turns raw data into meaningful information through reporting, dashboards, data visualizations, and analytics. Unlike traditional data analysis, which might focus on historical records, BI emphasizes real-time or near-real-time insights to guide strategic, tactical, and operational choices.

BI systems pull data from various sources—databases, CRM platforms, ERP systems, or even external market feeds—and integrate it into a cohesive format. Using advanced algorithms, statistical models, and user-friendly interfaces, BI tools enable stakeholders, from executives to frontline managers, to understand trends, identify opportunities, and address challenges.

The term “Business Intelligence” was coined in the 1960s, but it gained prominence in the 1980s with the rise of data warehousing and reporting tools. Today, BI encompasses a wide range of capabilities, from simple reporting to predictive analytics and artificial intelligence-driven insights.

Types of Business Intelligence

BI is not a one-size-fits-all solution. Depending on the organization’s needs, BI can take different forms. Below are the primary types of Business Intelligence:
