Campus Second-Hand Goods Trading Platform Design Based on BS

System architecture of campus second-hand goods trading platform uses the current popular B/S structure and uses the MVC three layer development mode, running on the Internet. Serve only needs to install this system and as long as the client users can get to the Internet, they can access this system through the browser to browse and publish a second-hand trading information, which saves complex installation, configuration and maintenance of the traditional C/S mode. System development is mainly divided into three parts. Java Beans is used to deal with business logic, JSP+HTML+JavaScript is used to manipulate the interface and configure the Servlet and SQL Server 2000 database access is completed through the JDBC-ODBC bridge. The system provides the service of commodity information management, shopping cart, management, online communication, answering and dynamic information display. The whole system makes full use of the modular design idea and development method and the testing results show the system is practical.
