What is Business Intelligence.
Business Intelligence (BI) refers to the tools, technologies, applications and practices used to collect, integrate, analyze, and present an organization’s raw data in order to create insightful and actionable business information.
Core of Business intelligence
Business Intelligence systems provide historical, current, and predictive views of business operations, most often using data that has been gathered into a data warehouse or a data mart and occasionally working from operational data.
BI is sometimes used interchangeably with briefing books, report and query tools and executive information systems. With these tools, business people can start analyzing the data themselves, rather than wait for IT to run complex reports. This information access helps users back up business decisions with hard numbers, rather than only gut feelings and anecdotes.
