Study Of Electronic Commerce System Based On Linux And Middleware Technologies

With the rapid development of computer technology and WWW(World Wide Web),the company and individual need to master the markets information rapidly, and response to the changes of the markets quickly. At the same time, the company will stick to reduce the complexity of the new EC(Electronic Commerce)solution in order to have a better future in the rapid development of world markets. It is necessary for the company to integrate old system with new EC seamlessly. It can not only make full use of the present investment but also take advantage of the EC. The middleware is the critical technology of building EC system. It is also an important applied field of middleware technology. What is more, it can give the company a good ROI(Return On Investment).This paper studies the architecture of EC system and middleware technology through analysis the present state of its applications, and puts forward the system design method and theory based on the middleware technology. It illustrates middleware and EC with eShop(Electronic Shop) prototype system in which introduces the concepts of Cluster and Connection pool. The solution for eShop based on middleware and flow of system is carried out. It accomplishes the eShop architecture design and middleware design. This paper also completes the selection of middleware for eShop archetype system class, coding and test work, etc. A complete prototype system for eShop is established.First, the thesis has briefly introduced the development of Linux OS, explained the operate system of Linux for the independence importance in industry in Chinese software and gives the researching background and main contents of the thesis. Then introduced the basic conception, model and their solving schemes for the electronic commerce .Discussed the electronic commerce application system construction , already from traditional 2 layers develop the N layer construction. Analyzed the current electronic commerce development technique present condition, think that adoption is in the center thata technique development electronic commerce system is a good project to resolve the live issue. Introduced later on in the Middleware technical and related theories, its category and applying fields. Introduced now three kinds of main middleware technique COM,CORBA and J2EE.Briefly introduced the middleware server - application server.The thesis introduced the eShop architecture system total design primarily. Introduced the choice of the mode of development first and in brief, then mak use of the mode of MVC to proceeded the structure design with the mode of JSF to the eShop architecture system. Analyzed the design project of the system to realizes with the software, include the development of the system construction, database design and in the middleware; emphasized to discuss in the middleware design and E.TB of the piece realizes. And to some key technique problem that realizes the inside proceeded the discussion. At the same time, still try to adopt the module to open the Web page - mean the layer.Finally, the thesis gives the conclusion and prospect of the future work. This paper will promote the usage of middleware technology into EC system. The theory and method of middleware technology discussed in this paper can also be applied to other fields .
