The System Of Network Game Point Card Directly Credited Online Based On E-Commerce Platform

Generally, large-scale E-Commerce Website is composed of THREE-ARY architecture. The low-level is a network platform. The middle-level is the basic platform for E-Commerce, including payment gateway interface, service center for customer. The high-level is various E-Commerce application systems.This paper mainly studies the subsystem of Network Game Point Card Directly Credited Online based on E-Commerce platform. That is how to analysis, design, and implement the subsystem through the concepts and methods of Object-Oriented Modeling.During requirements analysis for the subsystem, this paper mainly studies how to elaborately and correctly express entire business logic requirements, so that system analyst can be better to grasp the entire functional requirements for the subsystem from the macro level.During system analysis for the subsystem, this paper mainly carefully analysis and studies the domain model and application model of the subsystem. In the domain model, this paper applies class model and state model to elaborately and correctly analysis and describe the static structure of the subsystem. In the application model, this paper applies interaction model to elaborately analysis and correctly describe the entire function and behavior of the subsystem. Among the interaction model, use case diagrams respectively express the entire function of each part composed the subsystem; sequence diagrams and activity diagrams express the behavior and scenarios of each use case. Meanwhile this paper also applies application class model and application state model to describe the structure of the application control class and its meaningful state transitions, in which the main control class is the sequence class contained in the seller interface part of the subsystem. The control class has effect on many system behaviors, such as submitting order, allocating order, supplementing order.Finally this paper carefully analysis and studies the entire functional architecture and interact influences among different parts for the subsystem. And also describes the running environment of the subsystem, in which mainly describes sever, middleware, and other necessary functional packages required by the subsystem, such as activity package, order management package. During system implementation stage, this paper describes the database implementation of the subsystem; and describes the indexes designation, mainly due to their directly effect on the subsystem running effectiveness, especially during the time when the number of the access to the subsystem rises suddenly.
