校园二手交易平台
摘要
随着信息互联网购物的飞速发展，一般企业都去创建属于自己的电商平台以及购物管理系统。本文介绍了校园二手交易平台的开发全过程。通过分析企业对于校园二手交易平台的需求，创建了一个计算机管理校园二手交易平台的方案。文章介绍了校园二手交易平台的系统分析部分，包括可行性分析等，系统设计部分主要介绍了系统功能设计和数据库设计。
本校园二手交易平台有管理员，卖家和用户三个角色。管理员功能有，个人中心，用户管理，卖家管理，分类管理，求购信息管理，二手商品管理，我的订单管理，商品捐赠管理，捐赠信息管理，留言板管理，系统管理。卖家功能有个人中心，求购信息管理，二手商品管理，我的订单管理，商品捐赠管理，捐赠信息管理。用户功能有个人中心，求购信息，二手商品，我的订单管理，商品捐赠，留言反馈。因而具有一定的实用性。
本站是一个B/S模式系统，采用SSM框架作为开发技术，MYSQL数据库设计开发，充分保证系统的稳定性。系统具有界面清晰、操作简单，功能齐全的特点，使得校园二手交易平台管理工作系统化、规范化。
关键词：校园二手交易平台；SSM框架；MYSQL数据库
Abstract
With the rapid development of information Internet shopping, most companies create their own e-commerce platforms and shopping management systems. This article introduces the whole process of the development of the campus second-hand trading platform. By analyzing the needs of enterprises for the campus second-hand trading platform, a program of computer management of the campus second-hand trading platform was created. The article introduces the system analysis part of the campus second-hand trading platform, including feasibility analysis, etc. The system design part mainly introduces the system function design and database design.
This campus second-hand trading platform has three roles: administrator, seller and user. Administrator functions include personal center, user management, seller management, classification management, purchase information management, second-hand product management, my order management, commodity donation management, donation information management, message board management, and system management. Seller functions include personal center, purchase information management, second-hand product management, my order management, product donation management, and donation information management. User functions include personal center, purchase information, second-hand goods, my order management, goods donation, and message feedback. So it has a certain practicability.
This site is a B/S model system, using SSM framework as the development technology, MYSQL database design and development, fully guarantee the stability of the system. The system has the characteristics of clear interface, simple operation and complete functions, which makes the management of the campus second-hand trading platform systematized and standardized.
Keywords:Campus second-hand trading platform; SSM framework; MYSQL database
