Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
Management Center framework
The Management Center framework is the foundation for business user tooling. The business objects are defined by the individual components that make up the Management Center. The framework uses those definitions to provide all of the features that you can use to find, create, modify, and delete the defined business objects. If you plan to customize the Management Center, it is important to understand the framework and the components that make up the Management Center.
Management Center services
The Management Center framework uses different types of services to communicate with the WebSphere Commerce Server.

Management Center services

The Management Center framework uses different types of services to communicate with the WebSphere Commerce Server.

Each business object editor must define which type of service the Management Center will use to communicate with the WebSphere Commerce Server. Different types of services perform different tasks. For example, you can use configuration services to retrieve configuration data and context data, load services to retrieve business objects, and transaction services to create, update, and delete business objects.

The wcfService class is the base class for all service types used within the Management Center.
