Web portal
A web portal is a specially designed
website that brings information from
diverse sources, like emails, online forums
and search engines, together in a uniform
way. 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 (e.g., a
dashboard or map) and the chosen
implementation framework 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's
application programming interface (API) to
permit users to search intranet content 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 website 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
History

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. Netscape became a part of
America Online, the Walt Disney Company
launched Go.com, IBM and others
launched Prodigy (-only users.) Portal
metaphors are widely used by public
library sites for borrowers using a login as
users and by university intranets for
students and for faculty. Vertical markets
remain for ISV's (Independent Software
Vendors) offering management and
executive intranet "dashboards" for

corporations and government agencies in
areas such as GRC and risk management.
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.[1] A vertical portal (also
known as a "vortal") is a specialized entry
point to a specific market or industry
niche, subject area, or interest.[2] 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.
Personal
A personal portal is a Web Page at a Web
site on the World Wide Web or a local
HTML home page including JavaScript
and perhaps running in a modiﬁed Web
browser. A personal portal typically
provides personalized capabilities to its
Types

visitors or its local user, providing a
pathway to other content. It may be
designed to use distributed applications,
different numbers and types of
middleware and hardware to provide
services from a number of different
sources and may run on a non-standard
local Web server. In addition, business
portals can be designed for sharing and
collaboration in workplaces. A further
business-driven requirement of portals is
that the content be presented on multiple
platforms such as personal computers,
laptops, tablet computers, personal digital
assistants (PDAs), cell phones and
smartphones.

Information, news, and updates are
examples of content that could be
delivered through such a portal. Personal
portals can be related to any speciﬁc topic
such as providing friends information on a
social network or providing links to outside
content that may help others beyond your
reach of services. Portals are not limited
to simply providing links. Outside of
business intranet user, very often simpler
portals become replaced with richer
mashup designs. Within enterprises, early
portals were often replaced by much more
powerful "dashboard" designs. Some also
have relied on newer protocols such as
some version of RSS aggregation and may

or may not involve some degree of Web
harvesting.
Government
At the end of the dot-com boom in the
1990s, many governments had already
committed to creating government web
portal sites for their citizens. These
included primary portals to the
governments as well as portals developed
for speciﬁc branches (e.g., a particular
government ministry, department or
agency), or for speciﬁc sub-audiences
(e.g., senior citizens, parents, post-

secondary students, etc.). Notable
government web portals include:
australia.gov.au for Australia.
Disability.gov for citizens with
disabilities in the United States.
Europa (web portal) links to all EU
agencies and institutions in addition to
press releases and audiovisual content
from press conferences.
GobiernoUSA.gov for the United States
(in Spanish).
gov.uk for citizens & businesslink.gov.uk
for businesses in the United Kingdom.

Health-EU portal gathers all relevant
health topics from across Europe.
india.gov.in for India.
National Resource Directory links to
resources for United States Service
Members, Veterans and their families.
USA.gov for the United States (in
English).
Cultural
Cultural portals aggregate digitised
cultural collections of galleries, libraries
(see: library portal), archives and
museums. This type of portal provides a
point of access to invisible Web cultural

content that may not be indexed by
standard search engines. Digitised
collections can include scans or digital
photos of books, artworks, photography,
journals, newspapers, maps, diaries and
letters and digital files of music, sound
recordings, films, and archived websites
as well as the descriptive metadata
associated with each type of cultural work
(e.g., metadata provides information about
the author, publisher, etc.). These portals
are often based around a specific national
or regional groupings of institutions.
Notable cultural portals include:

Digital Public Library of America (in
development)
DigitalNZ – A cultural portal led by the
National Library of New Zealand
focused on New Zealand digital content.
Europeana – A cultural portal for the
European Union based in the National
Library of the Netherlands and overseen
by the Europeana Foundation.
TUT.by - A commercial cultural portal
focused on Belarusian digital content.
Corporate
Corporate intranets became common
during the 1990s. As intranets grew in size

and complexity, organization webmasters
were faced with increasing content and
user management challenges. A
consolidated view of company information
was judged insufﬁcient; users wanted
personalization and customization.
Webmasters, if skilled enough, were able
to offer some capabilities, but for the most
part ended up driving users away from
using the intranet. Many companies began
to offer tools to help webmasters manage
their data, applications and information
more easily, and by providing different
users with personalized views. Portal
solutions can also include workﬂow
management, collaboration between work

groups or branches, and policy-managed
content publication. Most can allow
internal and external access to speciﬁc
corporate information using secure
authentication or single sign-on.
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 (blog posts, comments, photos),
disparate data silos, and ﬁle formats,
information architects and taxonomists
will be required to allow users the ability to
tag (classify) the data or content. For
example, if a vice-president makes a blog
post, this post could be tagged with

her/his name, title, and the subject of the
post. Tagging makes it easier for users of
the intranet to ﬁnd the content they are
interested in. This will ultimately cause a
ripple effect where users will also be
generating ad hoc navigation and
information ﬂows. Corporate portals also
offer customers and employees self-
service opportunities.
Stock
Also known as stock-share portals, stock
market portals or stock exchange portals
are Web-based applications that facilitates
the process of informing the share-holders

with substantial online data such as the
latest price, ask/bids, the latest News,
reports and announcements. Some stock
portals use online gateways through a
central depository system (CDS) for the
visitors (ram) to buy or sell their shares or
manage their portfolio.
Search
Search portals aggregate results from
several search engines into one page. You
can ﬁnd search portals specialized in a
product, for example property search
portals. Library search portals are also
known as discovery interfaces.

Property search
Property search portals aggregate data
about properties for sale by real estate
agents. Notable property search portals in
the UK include Nestoria, Nuroa,
OnTheMarket, Rightmove and Zoopla.
Tender
A tender portal is a gateway for
government suppliers to bid on providing
goods and services. Tender portals allow
users to search, modify, submit, review
and archive data in order to provide a
complete online tendering process.

Using online tendering, bidders can do any
of the following:
Receive notiﬁcation of the tenders.
Receive tender documents online.
Fill out the forms online.
Submit proposals and documents.
Submit bids online.
Hosted
Hosted Web portals gained popularity and
a number of companies began offering
them as a hosted service. The hosted
portal market fundamentally changed the
composition of portals. In many ways they
served simply as a tool for publishing

information instead of the loftier goals of
integrating legacy applications or
presenting correlated data from
distributed databases. The early hosted
portal companies such as
Hyperofﬁce.com or the now defunct
InternetPortal.com focused on
collaboration and scheduling in addition to
the distribution of corporate data. As
hosted Web portals have risen in
popularity their feature set has grown to
include hosted databases, document
management, email, discussion forums
and more. Hosted portals automatically
personalize the content generated from
their modules to provide a personalized

experience to their users. In this regard
they have remained true to the original
goals of the earlier corporate Web portals.
Emerging new classes of Internet portals
called Cloud Portals are showcasing the
power of API (Application Programming
Interface) rich software systems
leveraging SOA (service-oriented
architecture, Web services, and custom
data exchange) to accommodate machine
to machine interaction creating a more
ﬂuid user experience for connecting users
spanning multiple domains during a given
"session". Cloud portals like Nubifer Cloud
Portal show what is possible using

Enterprise Mashup and Web Service
integration approaches to building cloud
portals.
Domain-specific
A number of portals have come about
which are specific to a particular domain,
offering access to related companies and
services; 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.
Overview
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
Engineering aspects

conﬁgurations may include load balancing
strategies. For portals that present
application functionality to the user, the
portal server is in reality the front piece of
a server conﬁguration that includes some
connectivity to the application server. For
early Web browsers permitting HTML
frameset and iframe elements, diverse
information could be presented without
violating the browser same-source
security policy (relied upon to prevent a
variety of cross-site security breaches).
More recent client-side technologies rely
on JavaScript frameworks and libraries
that rely on more recent Web functionality

such as WebSockets and asynchronous
callbacks using XMLHttpRequests.
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.
