what is web portal?

• Web portals provide a single point of access to a variety of content and core services, and ideally offer a single sign-on point.
• Portals often include calendars and to-do lists, discussion groups, announcements and reports, searches, email and address books, and access to news, weather, maps, and shopping, as well as bookmarks.
• Web portals offer advantages over home pages because they can offer user-specific, customized views.
• Roles help the portal determine your privileges for reading, searching, updating, adding channels, and personalizing content.
