Business Intelligence is in fact a set of tools and infrastructure that can be added value to the data of an organization by processing information. In fact, the core task of business intelligence processes is to turn data into value for an organization.

Business intelligence provides access and analysis of information that can help optimize the decisions and performance of a company or organization. Business intelligence is actually a system of interconnected activities related to data mining, online analytical processing, research and reporting, statistical optimization, and so on.
Companies use BI to improve their decisions, save on costs, and discover new business opportunities. BI is far more than collecting reports and nothing more than a set of tools for intelligent use of business systems. Companies use business intelligence to identify Best Practices and Lesson Learns that can be a good platform for re-engineering.
