The Online Shopping System Based On J2ee Architecture Design And Realization

With the development of network Internet technology , Electronic Commerce becomes the focal point , enterprise realizes Electronic Commerce already become possiblle. Not only the platform every enterprise is known to Electronic Commerce building enterprise level can broaden the enterprise camp selling a channel , but also the image waits for aspect to have important strategy meaning to lifting enterprise brand.The business pattern with the supportment of modern information technology already forms one kind of inevitable trend .On-line Shopping system as the foundation stone of the electronic commerce, will display the leading role to the future electronic commerce development ,and will develop into one of main trade method in 21 centuries step by step. The main target of on-line Shopping System designsing is to make use of modern electron and network skill in order to make the customer enjoy rapid convenient shopping way,build a interactive platform for enterprise and the customer,provide the enterprises one kind of brand-new marketing way. Joining World Trade Organization as well as the consummation of the security transaction standard and the electronic commerce activity laws and regulations will certainly impel on electronic commerce activity development such as on-line shopping in our country.In this thesis, the design focus is the public-oriented e-commerce system,on the basis of studying the on-line shopping e-commerce system at home and abroad,and through studying the analysis and optimization of the sale and purchase for the on-line shopping.Based on the studying of the J2EE architecture ,the thesis completed the designing of J2EE-based online e-commerce shopping system. For the features and objectives of Shopping System ,this task are mainly three-tier / multi-tier architecture. For the function demanding of the shopping system, the whole system is divided into user registration / login module, merchandise management module, Cart module, order processing module, promotions engine modules and online payment module.This thesis used a Hierarchical and componental designing methods.the system was studied designed and implemented. This system uses the EJB module ( Converse Bean, Entity Bean) mainly to solve the system elasticity, by facilitates the system service type and the business volume expansion in the extended design aspect. Through the working load balance, user may increase several new servers merely, and install server application software and the appropriate disposition then, do not need to apply carries on any revision when they expand the system. This will satisfy the request of expansion performance,and reduce the danger of the server collapsing. In addition, the system also has based on the J2EE construction other superiorityies like security, extendibility and the cross platform movement and so on.
