Design And Implementation Of Exchange Platform For Virtual Currency And Second-hand In Community Service And Management System

With the development of the Internet, as a special form of e-commerce, there ismore and more virtual currency. Then there are more and more people who demand toexchange virtual currency and old things. The establishment of networks ofcommunity-based on trading platform can bring to the community the convenience ofresidents. This paper designed and implemented a simple virtual currency and oldthings network switching platform to meet the above requirements,In this platform, all the community residents can join in, login, sell or buy things,and exchange their things. The web site will use the form of a list of items to displaythe demand and supply information to all the users. Once the user decides to changesomething, he only needs to contact the seller through the information of the seller.Then the two sides can agree to carry out a good time and place to make easyface-to-face transaction.The system uses MySQL as a database development platform, Tomcat networkinformation services as application servers, JSP (Java Server Pages) technology asdevelopment tools in Windows XP. It divides into two parts: front and backgroundpart. The front part is used by users, it includes individual center, the exchange ofinformation management and exchange goods inquiries, the exchange of protocolprocessing functions and other functions. The background part is used by theadministrators. It includes the administrator authentication, user management, andlink management. The web site is a dynamic, interactive e-commerce site that has thefunction of the provision of goods and systems management. This thesis emphasizes on the following problems,1. Overall structure design and interface flow design. Based on thecharacteristic of this platform, we tried to design and optimize thesystem's overall arrangement—dividing this system into interface partand background part. In this case, interaction between this platform couldbe well solved.2. Designing the database and optimizing the redundancy information. Tosolve the problem of heavy task, we emphasize on the optimization ofrelative data sheet. In this way, we could improve the accessing speed anddatabase reliability.3. Designing and optimizing the dynamic HTML script. Through using JSPand adapting methods to optimize the key script code, we are anticipatingimproving the trade response time and the platform's concurrent processability. Meanwhile, in the design, scalability should also be consideredseriously, in order to maintain the reusable of specific functions.Experiments show that the virtual currency and old things network switchingplatform has full functions, simple operation, stable operation and good practice. Atthe same time, it has certain reference value to other similar works.It describes the design and implement of the platform in detail:Chapter 1 describes the background and significance of the research, and thestructure of the paper.Chapter 2 introduces JSP(Java Server Pages) and the principle of it.Chapter 3 describes the system design and the module division, including systemdesign goals, system requirement analysis, function description and databaserequirement analysis. Chapter 4 describes the detailed design and implement, including system processand the implement of some modules.Chapter 5 describes the operation and debug of the platform, including the frontand background part.Chapter 6 describes a few ideas about how to improve the platform, and made asummary of the research.
