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。
