The concept of business intelligence was first put forward by GartnerGroup in 1996. Gartner Group defines business intelligence as: business intelligence describes a series of concepts and methods, and assists business decision-making by applying fact-based support systems. Business intelligence technology provides technologies and methods that enable enterprises to quickly analyze data, including collecting, managing and analyzing data, transforming these data into useful information, and then distributing them to all parts of the enterprise.

The implementation of business intelligence system is a complex system engineering, and the whole project involves many kinds of knowledge such as enterprise management, operation management, information system, data warehouse, data mining, statistical analysis and so on. Therefore, users must follow the correct implementation method to ensure the success of the project. The implementation steps of business intelligence projects can be divided into:
(1) requirement analysis: requirement analysis is the first step in the implementation of business intelligence. Before carrying out other activities, it is necessary to clarify the expectations and needs of enterprises for business intelligence, including the topics to be analyzed and the possible perspectives (dimensions) of each topic; It is necessary to discover the laws of those aspects of the enterprise. The needs of users must be clear.
(2) Data warehouse modeling: Through the analysis of enterprise requirements, the logical model and physical model of enterprise data warehouse are established, the application architecture of the system is planned, and all kinds of enterprise data are organized and classified according to the analysis theme.
(3) Data extraction: After the data warehouse is established, the data must be extracted from the business system to the data warehouse, and the data must be converted and cleaned during the extraction process to meet the needs of analysis.
(4) Establish business intelligence analysis reports: Business intelligence analysis reports need to be developed by professionals according to the format formulated by users, and users can also develop them themselves (the development method is simple and quick).
(5) User training and data simulation test: For the development and use of the separated business intelligence system, the use of the end users is quite simple, and the specific business problems can be analyzed only by clicking the operation.
(6) System improvement and perfection: The realization of any system must be continuously improved, especially the business intelligence system. After users use it for a period of time, more and more specific requirements may be put forward. At this time, it is necessary to reconstruct or improve the system according to the above steps.
