<div><p>IBM<sup>®</sup> offers
many products, such as WebSphere<sup>®</sup> Portal, that provide a portal environment
in which applications can be installed and run. A portal in simplistic terms
is a single point of access to multiple information sources. Each information
source is called a portlet. A portlet is one of the small windows or content
areas that appears on a portal page. </p>
<p>By putting portlets on a portal page, many "applications" or sources of
data can be displayed at once. Since an individual portlet can process data
from any available back-end server, a portal page provides consolidation of
data independent of data location or data format.</p>
<p>The individual portlets on a page may or may not be related. When portlets
are related, it is helpful when the portlets are able work together to perform
a set of tasks for the end user. Portlets that are able to communicate with
each other to perform related tasks are called cooperative portlets.</p>
<p>iSeries™ Access
for Web portlets provide portal functionality for accessing iSeries i5/OS™ resources.</p>
<p>The following topics contain more information about portlets and their
usage.</p>
