WebSphere Commerce integration with WebSphere Portal

You can integrate WebSphere Commerce, a Business Application Service with WebSphere Portal, an Interaction Service. The Interaction Service provides core portal services (WebSphere Portal) that aggregate applications and content and deliver them as role-based applications. The Enterprise Service Bus (ESB) pattern is used for communication, mediation, transformation and integration with external systems. Using an ESB to integrate the Web services exposed from WebSphere Commerce to the WebSphere Portal promotes a loosely coupled design where the ESB manages the interactions styles between the WebSphere Commerce services and the presentation layer. You do not need to alter the presentation layer to support the protocol and format used by the WebSphere Commerce services. Instead, you rely on the ESB to perform tasks such as message transformation and protocol mediation. Neither WebSphere Commerce nor WebSphere Portal needs to change in order to communicate with one another. The ESB is used to act as an interpreter between the two systems and will translate the messages into a format the receiving system understands.
