The Design and Implementation of Second-hand

Book-Selling System in Campus

Abstract

With the continuous development of the Internet, the network bookstore has brought people greatly convenience. Network bookstore is not only the development and supplement of the traditional bookstore, but also the trend of future development. But to the students in school, who have no salery, the cost of new books is more expensive, and second-hand book market has been becoming more and more active. The network of campus has become very mature, it’s necessary to develop a system used for the second-hand book dealing, to meet the needs of sellers and buyers, and improve book recycling and reduce students’ cost of buying new books.

This system is designed by the SH (Struts Hibernate) two-layer framework. Using Struts can be separated from the view layer and the control layer. Using Hibernate can achieve to manage database with object-oriented thinking. Using SH can achieve low coupling with the database and make the system more security and saclability. Functions of the system is mainly to release used books, search books’ information, leave comments, as well as the administrator to manage and maintain the system. There are three roles: system administrator users, registered users and unregistered users. The right of administrators is managing users, issuing bulletin and so on. Registered users can publish messages, leave comments. Unregistered users can only browse information. The realization of the system will make it more convenient for students. And at the same time it will comes to book recycling.

This thesis expounds the background and development trend of the campus secondhand books transaction platform. According to the software engineering development theory. A series of work have been done, such as system analysis and design, detailed summary design, coding, and testing of development. Finally realized the practical value of the Second-hand Book-Selling system in campus.

Keywords:Second-hand Book Deal, Struts, Database, Hibernate
