    一、实验题目
    实验背景:
    该项目立足于目前各大平台网站的番剧信息较为分散,用户需要辗转多个平台才能获取较为完整的番剧信息的背景下,实现了各大平台网站番剧信息的整合。将各大平台网站的番剧更新信息及番剧详情信息整合制表,展现在我们的网页上。
    二、开发环境
    系统:Ubuntu 20.08
    数据库:mysql 8.0.23
    编程语言: 【后端】 python, mysql 【前端】 html+css+js
    三、数据库设计
    3.1 需求分析
    3.1.1 番剧更新表
    系统维护在播新番的当前更新集数,播放地址链接,宣传图等内容。
    番剧更新主要来源于bilibiliACfun两个个网站。
    所有信息均通过爬虫以及python脚本进行动态维护。
    3.1.2 番剧详情表
    针对每个番剧,提供该番剧的详情信息,包括制作公司,监督,声优等内容。
    番剧详情主要来自于萌娘百科。
    信息通过爬虫python脚本动态维护
    3.1.1 用户管理
    系统用户分为超级管理员用户和普通用户。
    普通用户
    可查看数据库中的内容,可被授予删除、修改、添加番剧信息等权力。
    超级管理员
    拥有数据库的完全控制权,包括查看所有用户资料,创建新用户,用户授权等操作。

    # 该模块是用户管理模块
    # 主要提供数据库中的用户管理功能
    # 实现在数据库中进行用户创建、授权、修改、删除等具体操作
    # 该模块实现的功能供user模块封装调用
