项目介绍

随着我国经济活力的不断提升和互联网的快速发展，信息的重要性正在显现出来。电子商务作为经济发展的重要一环取得了突飞猛进的发展。由于具有高效便捷的优点，网上购物已经成为一种不可或缺的新型生活方式，依据面向对象的软件工程方法的流程进行开发。系统采用了当下流行的Django来作为后端开发框架，采用B/S架构进行开发，使用Mysql作为系统的存储模块来进行开发。系统设计包括管理员和普通用户两个角色用户，既为普通用户提供了商品浏览以及下单购买的服务，也让管理员有用户维护、商品维护、订单维护的平台。在系统开发完成后，采用完善的测试用例对系统平台进行测试，确保该系统是一个的各项功能都能够正常运行、性能良好的商城平台。
