It has evolved from executive information systems and decision support systems in the 1980s to include data warehousing, dashboards, analytics, and big data capabilities today. BI provides benefits like improved management and operations, better adjustments to trends, and the ability to predict the future. It has applications across private and public sector organizations. The BI process involves requirements analysis, data modeling, ETL, analytics, and presentation. Key components are the data warehouse, OLAP, data mining, and visualization tools like reports, dashboards, and scorecards. The global BI market is expected to grow significantly
