Term for a Web site that serves as entry point and location for structured search and content presentation. Historically, Web sites that provided a search engine targeted at the entire Web, added structures to ease the way users navigate through the Web. Over time, more and more features and services have been added to these Web sites such as free e-mail, personalization, and so on with the goal of keeping users on this Web site (which in turn helps selling advertising space). These sophisticated Web sites are now called portals. Popular examples of portals are www.lycos.com and www.yahoo.com. Nowadays, there are portals for all kinds of communities, and also Intranet portals such as SAPNet. With the mySAP.com Workplace™™ SAP offers a role-based enterprise portal that goes beyond classical internet portals.
