One of the benefits of using WebSphere Portal is the ability to deploy multiple portlets to a single page built using different solutions. With WebSphere Portal, it is possible to create an integrated web experience using a variety of tools that can be aggregated in one place.
For more information regarding WebSphere Portal development, refer to the following documentation:
For the use case website we describe in this wiki, the Government demo, we have a portal page which contains portlets that were built using IBM Web Experience Factory, Rational Application Developer and IBM Web Content Manager. This same portal page can be viewed using a desktop browser, a mobile web browser, or using an IBM Worklight hybrid mobile application that uses a device's native features.
We can render the same application differently depending on the requesting device type using a single code base.
