Then MVC model and J2EE frameworks are described briefly. And then based on the above theory, the status of enterprise and the characteristics of management, through analyzing the functional requirements of the system, the design an Invoicing System on the MVC pattern is provided with B/S architecture being used. After that, a comprehensive analysis of the system is conducted, and then analysis of the system's main flow. In designing stage, firstly the WEB design of the system is carried out and then overall design of Web layer, business logic layer, data persistence layer and also the design of database are conducted.
