Portal

What is a Portal?
A portal is a web-based application that acts as a gateway between users and a
range of different high-level services. It provides personalization, single
sign-on (SSO), content aggregation and customization features.
Portal is a single door or gateway that leads you to an array of sites. It is a
collection of links to other sites.
The idea of a portal is to collect information from different sources and
create a single point of access to information - a library of categorized and
personalized content. It is very much the idea of a personalized filter into
the web.
Portals normally consist of different Portlets to process different consumer
requests to these services and generate dynamic content from the responses.
Portlets are used in portals as self-contained pluggable user interface
components to the services. Portlets can be developed in different languages.
How a Portal Page is Created?
Figure below shows how the separate Portlets are assembled by the Portlet
container to create the page.
Each Portal page is made up of one or more Portlet windows.
EXAMPLE:
One good example of an Internet portal is my.yahoo.com. My Yahoo! is your
personal gateway to your frequently visited pages in Yahoo! and the Web. You
personalize it and choose what you want to see, like email, news, weather,
stock prices, sports scores, TV and Movie Listings, and much more, all in one
place.
If you take a close look at this page, you will see that this page is made up
of different “windows”. There is one window for today’s news, another window
for top stories, a third for bollywood movie news, and so on. Each of these
windows represents a Portlet. Also each window has a title bar and a few
buttons to refresh, editing preferences and deleting of that Portlet (module)
separately.
Actually these windows are different applications developed independently of
each other. If the end user is not interested in sports update, he can replace
this with his area of interest say stock quotes. Each of these windows /
components represents a Portlet.
Classification of Portals:
Portals are broadly classified as Enterprise Information Portal and Content
Management Portal. Often, both types are combined and deployed together in
order to meet the business needs.
• Enterprise Information Portals are primarily intended to consolidate many
different types of information from a multitude of sources onto a single
screen. The users of this information typically do not publish to this type of
portal; rather, they are the consumers of the information prepared and
published by others.
Example: Corporate program announcements and events, reports that enable users
to acquire information on stock quotes, News and Weather reports etc.
• Content Management Portals are designed to improve the access and sharing
information. In a content management portal, self-service publishing features
allow end users to post and share any kind of document or web content with
other users. Nearly every user has the ability to add documents to the portal;
certain users have privileges to modify documents produced by other users or
groups. As opposed to enterprise information portal the majority of users are
empowered to both publish and retrieve information within the portal framework.
