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.

Question and answer tree
When you set up the Guided Sell metaphor, you create a list of questions and answers for each category of product data. Answers can lead to follow-up questions, and each of those questions then presents another set of answers. The questions and answers are arranged in a tree structure, called a question and answer tree.

Question and answer tree

When you set up the Guided Sell metaphor, you create a list of questions and answers for each category of product data. Answers can lead to follow-up questions, and each of those questions then presents another set of answers. The questions and answers are arranged in a tree structure, called a question and answer tree.

Customers do not actually see the tree; they are presented with only one question and set of answers at a time. Depending on how customers answer the first question, they will traverse different branches of the tree.
