1、项目介绍
随着人们生活水平的高速发展，电子产品销售方面在近年来呈直线上升，人们也了解到电子产品的实用性，因此电子产品的销售数量也逐年递增，电子产品销售的增加加大了在管理上的工作难度。为了能更好的维护电子产品销售管理秩序，同时提高工作的效率、确保每一用户都能得到有效的保护，在进行全面调研、探求实际情况之后本人设计并实现了基于Python的电子产品销售系统可视化销量统计。
基于Python的电子产品销售系统可视化销量统计采用了Python技术(也有Java技术，做了两版)、Django框架(SpringBoot )，连接MySQL数据库，具有较高的信息传输速率与较强的数据处理能力。包含管理员和用户两个层级的用户角色，系统管理员可以对个人中心、用户管理、产品类别管理、电子产品管理、留言板管理、系统管理、订单管理等功能进行详情，修改和删除操作；真正实现了管理工作的无纸化，并且还拥有角色及用户的添加与删除功能，可以很好的供所有用户使用。在对系统进行测试之后，确定可以实现所有预想的功能，并且可移植性强，可以很好的起到电子产品销售管理的作用。
2、核心功能模块
E-R图即实体-联系图，主要作用是提供了解显示数据类型存在的联系的途径，是藐视现实世界的概念模型，其关键要素是实体型、属性、联系。以下是本系统主要的实体图，如下图所示。
电子产品实体图
留言板实体图
购物车实体图
订单实体图
3、项目展示
当人们打开系统的网址后，首先看到的就是首页界面。在这里，人们能够看到系统的导航条，通过导航条导航进入各功能展示页面进行操作。系统首页界面如图所示：
电子产品：在电子产品页面的输入栏中输入产品名称、品牌和选择产品类别进行查询，可以查看到电子产品详细信息，并根据需要进行添加到购物车、立即购买、评论或收藏操作；电子产品页面如图所示：
购物车：在购物车页面可以查看到商品名称、图片、价格、数量、总价等详细信息，并进行点击购买或删除操作；购物车页面如图所示：
管理员点击电子产品管理。在电子产品页面输入产品名称、品牌和选择产品类别进行查询、新增或删除电子产品列表，并根据需要对电子产品详情信息进行详情、修改、查看评论或删除操作；如图所示：
