Business Intelligence (BI) signifies the tools and systems that play a key role in the strategic planning process within an organization. It refers to a set of approaches and techniques that are used by organizations for tactical and strategic decision making. It leverages technologies that focus on counts, statistics and business objectives to improve business performance. BI can be thought of as a data refinery that turns data into actions and business value. Smart companies in the 21st century use business intelligence (BI) solutions to gain a stronger picture of their internal operations, customers, supply chain, and financial performance. They also derive significant ROI by using BI to devise better tactics and plans, respond more effectively to emergencies, and capitalize more quickly on new opportunities.
