WebSphere Commerce runtime framework enhancements
http://publib.boulder.ibm.com/infocenter/wchelp/v6r0m0/index.jsp
New to this release is the further decoupling of the presentation tier from the business logic tier to better enable support for multiple sales channels.
requests can enter the WebSphere Commerce Server from different types of clients such as a rich client, kiosk or as a browser request.
In previous releases of WebSphere Commerce the framework was designed for Web-based transactions.
The framework enhancements in this release support multiple presentation layers, responsible for displaying results, which decouple control logic from business logic.
