A WEB PORTAL is a specially designed website that brings information together from diverse sources in a uniform way like emails, forums, and search engines etc. Usually, each information source gets its dedicated area on the page for displaying information (a portlet ); often, the user can configure which ones to display. Variants of portals include mashups and intranet "dashboards" for executives and managers. The extent to which content is displayed in a "uniform way" may depend on the intended user and the intended purpose, as well as the diversity of the content. Very often design emphasis is on a certain "metaphor" for configuring and customizing the presentation of the content and the chosen implementation framework and/or code libraries. In addition, the role of the user in an organization may determine which content can be added to the portal or deleted from the portal configuration.
A portal may use a search engine API to permit users to search intranet as opposed to extranet content by restricting which domains may be searched. Apart from this common search engines feature, web portals may offer other services such as e-mail , news, stock quotes, information from databases and even entertainment content. Portals provide a way for enterprises and organizations to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different web entities at various URLs . The features available may be restricted by whether access is by an authorized and authenticated user (employee, member) or an anonymous site visitor.

In the late 1990s the
Web portal was a Web IT buzzword. After the
proliferation of Web browsers in the late-1990s many companies tried
to build or acquire a portal to attempt to obtain a share of an
Internet market. The
Web portal gained special attention because it
was, for many users, the starting point of their Web browsing if it
was set as their home page. The content and branding of a portal could
change as Internet companies merged or were acquired.
Web portals are sometimes classified as horizontal or vertical. A horizontal portal is used as a platform to several companies in the same economic sector or to the same type of manufacturers or distributors. A vertical portal (also known as a "vortal") is a specialized entry point to a specific market or industry niche, subject area, or interest. Some vertical portals are known as "vertical information portals" (VIPs). VIPs provide news, editorial content, digital publications, and e-commerce capabilities. In contrast to traditional vertical portals, VIPs also provide dynamic multimedia applications including social networking, video posting, and blogging.

GOVERNMENT WEB PORTALS
At the end of the dot-com boom in the 1990s, many governments had already committed to creating portal sites for their citizens. These included primary portals to the governments as well as portals developed for specific audiences. Examples of government Web portals include:

Many companies began to offer tools to help webmasters manage their
data, applications and information more easily, and through
JSR168 Standards emerged around 2001. Java Specification Request (JSR) 168 standards allow the interoperability of portlets across different portal platforms. These standards allow portal developers, administrators and consumers to integrate standards-based portals and portlets across a variety of vendor solutions.
The concept of content aggregation seems to still gain momentum and portal solution will likely continue to evolve significantly over the next few years. The Gartner Group predicts generation 8 portals to expand on the Business Mashups concept of delivering a variety of information, tools, applications and access points through a single mechanism.
With the increase in user generated content, disparate data silos, and file formats, information architects and taxonomist will be required to allow users the ability to tag (classify) the data. This will ultimately cause a ripple effect where users will also be generating ad hoc navigation and information flows.
Corporate Portals also offer customers a prime example of this trend would be the growth in property portals that give access to services such as estate agents , removal firm , and solicitors that offer conveyancing . Along the same lines, industry-specific news and information portals have appeared, such as the clinical trials-specific portal .
The main concept is to present the user with a single Web page that brings together or aggregates content from a number of other systems or servers.
The application server or architecture performs most of the crucial functions of the application. This application server is in turn connected to database servers, and may be part of a clustered server environment. High-capacity portal configurations may include load balancing strategies.
The server hosting the portal may only be a "pass through" for the user. By use of portlets , application functionality can be presented in any number of portal pages. For the most part, this architecture is transparent to the user.
In such a design, security and concurrent user capacity can be important issues, and security designers need to ensure that only authenticated and authorized users can generate requests to the application server. If the security design and administration does not ensure adequate authentication and authorization, then the portal may inadvertently present vulnerabilities to various types of attacks.
