Design And Implementation Of Yantai University Campus E-commerce System

Based on the thought of the New Generation ERP, a componentized and distributed ERP software engineering framework is designed and developed in this research project through adopting JAVA EE technology. It is also expected that the framework presented in this project will be suitably utilized in medium-and-large-sized enterprises.This ERP technological framework can fulfill the quick construction and assignment of modern enterprise application system. The framework provides an encapsulated public commercial package, which fully reflects the irrelative relationship between enterprise management and actualized technology. Besides of these, since the majority tasks within general logic has been provided by the technological framework, there will be no necessity to develop the hardest realization part and mass repeated business logic. Therefore, through using this framework, the workload of the developing enterprise will be dramatically reduced. The developer and implement personnel can concentrate on customer special business logic and the fulfillment of management mode. As a result, the expedited system assignment and the accelerated implement speed will greatly shorten the cycle time.It is noticed that a unified API is provided in this framework as well. This unified API, can not only make the framework effectively integrate with enterprise’s original application system and the third party’s application system, but also enables the operation object transfer and data integration & share between them.To improve repeatability, maintainability and expansibility of the whole of framework, along with reducing coupling among each layer, the framework adopts the MVC design mode plus introducing Listener before business layers to fulfill the transmitting of incidents. Further, the DAO design the mode is also applied for encapsulation business logic. This is done through using stateless Session EJB technology under container management to support the distributed and componentized module construction, so does the facilitated and safe operation control. Moreover, to raise the efficiency and to reduce the consumption of systematic resources, both Catch technology, which is used for resource buffering, and the EventResult which is designed through using Value Object mode for network data transmission are utilized in the framework as well.
