Research And Implementation Of The E-commerce System Based On P2P Network

E-commerce system is a special kind of application system which is built on the technology of Internet information.Under the e-commerce systems,both sides of trading could go across barriers of both time and distance to negotiation,exchange goods and services.With the continuous development of e-business applications,the scale of the e-commerce systems is expanding,which is bring enormous challenges to system's development and maintenance.Peer-to-peer technology is the product of combination of the computer network and the distributed computing technology.Peer-to-peer technology has certain advantages in the field of large-scale distributed applications.File sharing,instant messaging,collaborative computing,distributed data access network technologies,is its typical application.It will be a new research direction to use the technical advantages of peer-to-peer technology to solve some problems in e-commerce application.This thesis analyzed the constituent elements of e-commerce systems,and then combined the E-commerce and peer-to-peer technology together.Made preliminary studied building E-commerce application systems in the environment of peer-to-peer.built the theoretical model based on the open-source project JXTA. Analyzed and designed the framework of the system.The main function module of the prototype system has been implemented.In this paper,the main works include:(1) Analyzed the constituent elements of e-commerce systems.Pointed out that what the main functions is which must be achieved by each sub-system,when we build the e-commerce application in peer-to-peer environment.Analyzed the traditional C2C(Consumer-to-Consumer) e-commerce model,proposed the C2C-like e-commerce model,and C2C-like architecture of third-party services.(2)Proposed the theoretical model of the system,including the definition of the system,the overall framework,the running model of system.(3)Design and implementation of the DataCenter subsystem,including requirement analysis and use case analysis,proposed the DataCenter subsystem architecture,focusing on the realization of the architecture of the main functions of DataCenter subsystem modules,including data management,and information search and publishing modules.(4) Design and implementation of the TradeManagement Center subsystem. Proposed the whole framework of the subsystem and the implementation of function modules of JXTA extend layer,business Logic layer,business management layer,and system configuration management etc.
