篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了管理信息系统 课程设计相关的知识,希望对你有一定的参考价值。
一、系统概要说明:
此网站的设计目的主要是为用户提供一个分享生活趣事的平台,现今,短视频类APP发展迅猛,但文字类分享平台由于微博的存在一直止步不前,但微博已经过于商业化和演艺化,网民急需一个纯净的文字分享平台。此系统中,用户通过注册后不仅能够查看、评论、点赞他人的文章,也可以分享自己的故事,以达到交互的作用。用户还可以在系统内对想要浏览的文章进行关键字搜索和分类搜索,以达到便捷、准确的人性化服务。系统的设计包括用户注册、登录、首页、发帖、搜帖、浏览、点赞、评论、个人中心等等,通过Pycharm和mysql实现上述功能。
二、网站结构设计:
网站设计了注册、登录功能,以便保存用户个人信息和足迹。本网站以分享为主,为保证用户能够方便快捷的寻找到所需要的文章,网站不仅设计了关键字搜索,还设计了文章分类查找和根据发表年限查找。为体现部分文帖的受众程度,激励用户书写有质量、有意义的文章,网站首页设计了推荐文帖,根据文章的浏览总量进行推荐。文章内部,网站设计了用户可以查看发布的文章的详情内容,阅读后可以增加浏览量,也可以对文章进行点赞、评论和收藏。具体内容和功能如下:
- 用户注册:针对新用户,注册账号时,对密码进行二次验证确认,帐号信息
- 存入数据库;
- 发布文章:用户通过书写标题和正文进行文章发布,并同时选择文章所属类
- 别,方便读者通过分类搜索找到文章;
- 阅读文章:用户通过点击文章标题进入文章详情页,贡献一点阅读量,详情
- 页内,详情页不仅会显示文章的正文,还会注明文章的作者、点赞量、评论情况等,用户自己也可对文章进行评论、点赞、收藏;
- 推荐文章:网站自动根据文章的阅读量进行文章推荐,显示在首页推荐栏中,
- 根据作者的总浏览量将作者名字显示在推荐作者栏中;
- 搜索文章:用户可根据想查看文章的题目进行精确搜索,也可以通过搜索想
- 查看文章的类别或者发表年限进行分类查找;
- 个人中心:用户在个人中心页面可以查看自己所发布的文章、点赞的文章、
- 收藏的文章和评论的文章以及用户个人的帐号、昵称、编号等信息,另此,用户也可在此界面更换头像或者修改密码,点击修改密码,跳转到单独页面,保证了用户个人信息的安全性。
三、网站结构模块图:
四、各模块、页面详解:
- 用户注册,针对新用户,注册账号时,对密码进行二次验证确认,
帐号信息存入数据库;
