1、项目介绍
在Internet高速发展的今天，我们生活的各个领域都涉及到计算机的应用，其中包括疫情数据可视化分析系统的网络应用，在外国线上管理系统已经是很普遍的方式，不过国内的管理系统可能还处于起步阶段。疫情数据可视化分析系统具有疫情数据可视化分析信息管理功能的选择。疫情数据可视化分析系统采用Django框架，基于mysql开发，实现了首页、个人中心、用户管理、员工管理、疫情信息管理、核酸检测管理、检测预约管理、检测结果管理、行程信息管理、系统管理等内容。
本次设计任务是要设计一个基于Python的疫情数据可视化分析系统，通过这个系统能够满足疫情数据可视化分析的管理员、员工和用户的疫情数据可视化分析分享功能。管理员可以根据系统给定的账号进行登录，登录后可以进入疫情数据可视化分析系统，对疫情数据可视化分析系统所有功能进行管理。
2、核心功能模块
通过前面的功能分析可以将疫情数据可视化分析系统的功能分为管理员、员工和用户三个部分，系统的主要功能包括首页、个人中心、用户管理、员工管理、疫情信息管理、核酸检测管理、检测预约管理、检测结果管理、行程信息管理、系统管理等内容。任何用户只要进入系统不需登录也可浏览到的信息，后台管理是针对已登录的用户看到满意的疫情数据可视化分析信息而设计的。
1、一般用户的功能及权限
所谓一般用户就是指还没有注册的过客,他们可以浏览主页面上的信息。但如果有中意的疫情数据可视化分析信息时，要登录注册，只有注册成功才有的权限。
2、管理员的功能及权限
用户信息的添加和管理，疫情数据可视化分析详细信息添加和管理，文档信息添加和管理以及系统信息管理，这些都是管理员的功能。
基于Python的疫情数据可视化分析系统的整个设计结构如下图所示。
