Business intelligence systems collect data from the various data warehouses in an organization and provide management with analyses according to lines of business, department or any breakdown that management desires. For example, financial institutions use BIS systems to develop credit risk models that analyze the number and extent of lending or credit given to various sectors. These systems may use various techniques and formulas to determine the probability of loan defaults.

Because intranets and extranets share the same technology and software platforms as the Internet, they are easy and inexpensive ways for companies to increase integration and expedite the flow of information within the company (intranets alone) and with customers and suppliers (extranets). They provide ways to distribute information and store corporate policies, programs, and data. Both types of nets can be customized by users and provide a single point of access to information from several different systems. Businesses can connect the nets to transaction processing systems easily and quickly. Interfaces between the nets and TPS, MIS, DSS, and ESS systems provide input and output for users.
