The Research And Implementation Of Electronic Commerce System Based On EJB Component

With the increasing popularization and extensive application of e-commerce, the traditional enterprise development platform is now facing flinty challenges. Because of the complex internal logic of e-commerce, the rigorous security demand and the quick changes of the commercial form, the development platform should provide enough complexity and flexibility to adapt the demand of e-commerce. In order to adapt this kind of demand, the recent evolution of EJB component technology based on J2EE platform has paved the way for system development to become an increasingly new trend in the coming years, especially for e-commerce.According to the research background of Nanchang Unicom's actual conditions, the e-commerce system of Nanchang Unicom was implemented on the basis of EJB component in J2EE four-tier system architechture by use of visual Jave development kit IBM Websphere platform and large-scale DBMS. The system offers the on-line shopping, on-line transaction and platform of payment for enterprises, trade companies and consumers.Firstly, it is discussed in this essay that the e-commerce, its trend, the related technologies of e-commerce and the feasibility of system. Secondly, it is researched deeply EJB component, it is also compared the other distributed components, then, it is described the system following the approach of lifecycle, research, design and implementation of software, and combing the business demand and characteristic of system. Total system structure, function target and user case analysis are included in analysis period. Thirdly, it is deeply researched about the E-commerce security. Fourthly, it is discoursed that the design of system structure, database and the EJB module, the realization of the system is also discoursed. At last, it is concluded that the current research result, it is also expected that the further research and work.
