文末获取资源,收藏关注不迷路
随着网络和计算机技术的发展,各行各业出现了新的生机。各种办公软件和网站充斥到日常生活中,并在实践中不断的进步和发展。目前办公软件和网站技术已非常成熟,可以为用户提供更好的工作帮助。网上购物网近几年成为热门,对于商品的购买的途径最常用的有代购、自己去实地购买和网上购买。自己去实地购买一般适合有空闲时间的人们,代购虽然是大多数用户的最佳选择,但由于代购环节不透明而使大部分人们放弃。网上购买的使用量非常高,相对应的管理工作也增加。到目前为止,人们网上交易一般去淘宝、京东等平台。这类平台属于第三方平台需要大量的推广费用,造成商家成本增加而使很多的商家望而却步。
本线上购物系统采用网上购物模式进行商品的销售,编程语言采用python语言,数据库为mysql,运行软件为Pycharm。本系统包括用户和管理员,用户可以在系统中查看商品信息进行购买,可以进行评价、收藏和管理订单信息;管理员可以管理网站的商品、商品的类型、订单信息。为了保证系统的健康和正向发展,管理员可以对注册用户的资料进行审核。本系统实现了商品的网上销售,减少员工的工作量,提高用户购买的效率和适应时代发展。
如今的时代是信息化的时代,更种信息大爆炸。人们的基本工作生活中都离不开网络和计算机,现如今各类网站、管理系统、app都快速发展,为人们带来更便捷的生活体验。网站类的系统有宣传类网站、企业类网站、购物类网站,其中使用率最高也最贴近人们生活的是购物类网站,像淘宝、京东,用户量非常大;管理类系统有库存管理系统、会计管理系统、收银管理系统等,使用率也非常大;app类的有美团、拼多多等,都为人们的生活带来了便捷。
商品为每天的必须品,对于商品的购买人们一般都是去商店购买。这种方式需要大量的时间,在销售的高峰期时也有很多的用户排队。对于特定商品还需要大量的时间。这样的现象就导致了代购的出现,制假现象层出不穷,带来了社会不稳定因素。虽然现在也有正规的网上交易网站,但网站属于第三方,需要大量推广费用,增加商家成本。对于特定商品的购买还有一部分是采用自己去销售地,这类方式虽然质量保证,但要求人们拥有足够的时间和出行成本,也不是最优的解决办法。
目前国家正处于高迅发展的时代,网络已发展到5G,使上网更加快速。网站反应缩短到1秒内,让更多的用户越来越依赖网站。人们对生活品质要求也越来越高,现在也有很多的企业、商家还采用传统的办公管理方式,这类方式对于管理小规模的事项非常便利,信息量少、工作内容少,统计简单。但随着要管理的事项越来越复杂,如果还采用传统的人工管理方式会带来更多的工作错误,使工作花费更多的时间,但实现的效果并不好。所以紧跟时代发展才可以保证更好的工作效率,体现更多的工作价值。
如今是网络和信息化的时候,所有的事务都可以由计算机、网络来管理。商品的销售同样可以实现。采用网上的购买系统可以实现24小时购买,商品的查询也更为方便,出错率也更低。计算机对于信息处理更为高效、准确,也就可以提高工作人员的工作效率,把单一重复性的工作交由计算机来处理,解放工作人员双手,提高工作热情。网上的购买系统可以使商品信息化,实现购买的自动化,用户自主下单,不需要工作人员,减少商家的销售成本,从而提高经济效益。
使用说明
使用Navicat或者其它工具,在mysql中创建对应名称的数据库,并导入项目的sql文件;
使用PyCharm 导入项目,修改配置,运行项目;
将项目中config.ini配置文件中的数据库配置改为自己的配置,然后运行;
运行成功后,在浏览器中输入:http://localhost:8080/项目名
本python+django+vue+Elementui+mysql系统可以定制,采用pycharm开发,基于web的B/S架构设计完成,充分保证了系统代码的良好可读性、实用性、易扩展性、通用性、便于后期维护、操作方便以及页面简洁等特点,覆盖知识面大,非常适合作为计算机专业的同学参考资料进行学习.主要编程语言为python和mysql,框架是django,有代码视频讲解参考,包安装调试,包本地部署成功.
为了系统可以实现用户的要求和工作人员的要求,去实际调查和参加销售工作,得出本系统的服务对象为需要商品的用户和商家的工作人员,本系统的基本信息为订单信息和商品信息,根据不同的使用对象设计不同的功能。管理员的功能为:
(1) 商品评价管理功能,查询商品评价和删除商品评价;
(2) 订单管理功能,审核用户的订单;
(3) 商品信息管理功能,调整和发布商品;
(4) 商品类型管理功能,可以管理商品的类型和添加、删除商品的类型;
(5) 会员管理功能,审核用户的注册信息;
(6) 个人中心管理功能,可以实现管理员信息的管理。
用户功能有:
(1) 用户注册功能,方便用户购买和评价使用;
(2) 用户登录功能,登录后才可以进行购买、收藏、评价;
(3) 商品信息功能,浏览商品进行购买;
(4) 订单管理功能,管理购买信息;
(5) 商品评价功能,可以发表自己的使用心得;
(6) 购物车功能,可以实现多种商品一起下单;
(7) 我的信息功能,可以修改自己的资料。
