Organizations have, over the years, successfully employed business intelligence tools like OLAP and data warehousing to improve the supply of business information to end users for cross industry applications like finance and customer relationship management, and in vertical markets such as retail, manufacturing, healthcare, banking, financial services, telecommunications, and utilities. In the recent years, the Internet has opened up an entirely new channel for marketing and selling products. Companies are taking to e-business in a big way. The issue facing end users as organizations deploy e-business systems is that they do have not had the same business intelligence capabilities available to them in e-business systems as they do in the traditional corporate operating environment. This prevents businesses from exploiting the full power of the Internet as a sales and marketing channel.
As a solution, vendors are now developing business intelligence applications to capture and analyze the information flowing through e-business systems, and are developing Web-based information portals that provide an integrated and personalized view of enterprise-wide business information, applications, and services. This advanced business intelligence systems are called E-intelligence systems.
