Communications of the ACM, 45 (10):
77-82 (October 2002)Abstract
Both on the Web and on internal networks, there is an increasing effort to connect computer systems. The reasons for this are widespread, but there are two major themes behind these reasons. The first theme is e-business, which is motivating companies to expose their business processes over the Weh. This
mails linking their core business systems to the Web site. As e-business and the Web have developed, more and more integration is heing pushed through the
portal model. In the portal model, a single Web site becomes a desktop at which users can access the main systems, functions, and data they need. For example: a Web portal might offer news, stock prices, sports results, weather, shopping and travel information from a single Web site; a developer portal could offer developers access to the code, compilers, GUI tools, and documentation they need to do their jobs; and a business portal may offer business data, marketing and sales information, stock levels, access to Web site hit statistics, and trade information. All these activities require integration.
