More about Web Portals : A web
portal is a site that functions as a point of access to information on
the World Wide Web. Portals present information from diverse sources in
a unified way. Aside from the search engine standard, web portals offer
other services such as news, stock prices, infotainment and various
other features. Portals provide a way for enterprises to provide a
consistent look and feel with access control and procedures for multiple
applications, which otherwise would have been different entities

A personal portal is a site on the World Wide Web that typically
provides personalized capabilities to its visitors, providing a pathway
to other content. It is designed to use distributed applications,
different numbers and types of middleware and hardware to provide
services from a number of different sources. In addition, business
portals are designed to share collaboration in workplaces. A further
business-driven requirement of portals is that the content be able to
work on multiple platforms such as personal computers, personal digital
assistants ( PDAs ), and cell phones.

centralized application that has access to various other
applications within the same enterprise to share the
information across the applications. Also the various users
with different roles accessing the different applications
prefer to have a single access point to all of them over the
Internet. They like to personalize the applications and have
the coupled applications coordinated. Above all, the
administrator users like to have administrative tools all in a
single place to administer all the applications. All these are
achieved through portals. Since all the applications share
information through portals, there is better communication
between various types of users. Another advantage of portals
is that they can make event-driven campaigns. Below is
