They are object WEB that uses Java applet as CORBA clients and four layers architecture that uses JavaBean as CORBA clients. The e-commerce systems that make use of four layers architecture have many advantages of being reliable, simple, transportable, reusable and secure.In section four, I describe how to design and implement e-commerce system that utilize four layers architecture through an example of a simulated network bookstore.I narrate the innovative points, insufficiency and the farther research of this article in section five.
