Introduction to business intelligence
The term business intelligence (BI) refers to the use of company data to facilitate decision-making by decision-makers, i.e. understanding current functioning and anticipating actions for well-informed steering of the enterprise.
Intelligence tools are based on the use of an intelligence information system which is supplied with different data extracted from production data, information concerning the company or its environment and economic data.
A tool called ETL (Extract, Transform and Load) is therefore responsible for extracting data from different sources, cleaning them up and loading them into a data warehouse.
Finally, analytic intelligence tools make it possible to model the representations on the basis of queries to create border tables, this is called reporting.
