The Design And Realization Of Campus Secondhand Transaction Network

With the development of network technology, E-commerce transactions are risingyear by year, traditional secondhand transaction market also shows new vitality andvigor on this platform. Due to its recruit of numerus new students and the graduation ofmany students, university campus has a large second hand transaction market. At themeanwile, students have a strong sense of shopping on the internet and saving. Basedon what is mentioned above, this paper takes the situation of beginning and ending ofuniversity terms into consideration, discusses the state-of-the-art and theory basis ofcampus secondhand tansaction websites, designs and develops a complete campussecond hand tansaction website. I hope the building and researching of this system canserve a conservation-minded society, facilitates the secondhand transaction amongteachers and students.Before developing the complete system, I searched and gathered information aboutcampus secondhand transaction, analyzed college students’ trading psychology, gotknown about the situation abraod and demonstrated the feasibility of the project. Thispaper uses standard Unified Modeling Language(UML), darws use case diagram to dosystem analysis, uses package diagram, component diagram, physical architecturediagram,class diagram, object sequence diagram to build a complete system design andwebsite design, and also detailly analyzes system data storage requirements, I also useother assistive technology to express the problem more clearly.In this paper, the campus secondhand transaction website is developed usinggeneral B/S architechture. On the server side, I choose the widely used open sourceplatform Apache+MySQL+PHP. On the client side I choose technologies includingHTML, CSS and JavaScript. The system contains two main modules: the websitemember module in the front stage and management module in the back stage. Frontstage module contains functions like page view, transaction release, transactionmanagement, information release and register login. Back stage module realizesfunctions like manager management, value-added service management, front stagemember management and transaction information management. Using this websitesystem, we can realize all the basic functions of transaction website except payment. Italso satisfies the characteristic order online, trasaction offline that campus secondhand tranction has.According to the software life cycle theory, this paper analyzes the strength andshortage of the website with a disscusion of its potential value and also map out itsfuture.
