Business Intelligence
Business Intelligence (BI) is a broad category of applications and technologies that capture, store, and analyze data. To make informed business decisions based on accurate and up-to-date information, intuition is not enough. Data analysis, reporting, and querying tools can help business users handle large amounts of data and extract valuable information.
BI applications include decision support, query and reporting systems, online analytical processing (OLAP), statistical analysis, forecasting, and data mining.
