Business Intelligence Software is a tool that utilises existing data of an enterprise for making wise business operation decisions. The business intelligence system assembles all data from other business systems of the enterprise. Take a commercial enterprise as an example. The business intelligence system includes business orders, inventory, transaction accounts, customer and supplier information, industry and related data as well as other external environmental data. These data may come from business systems such as the enterprise's CRM, SCM, purchase, sales, or inventory records.
