随着信息互联网信息的飞速发展,无纸化作业变成了一种趋势,针对这个问题开发一个专门适应师生作业交流形式的网站。本文介绍了知识管理系统的开发全过程。通过分析企业对于知识管理系统的需求,创建了一个计算机管理知识管理系统的方案。文章介绍了知识管理系统的系统分析部分,包括可行性分析等,系统设计部分主要介绍了系统功能设计和数据库设计。
本知识管理系统有管理员和用户两个角色。管理员功能有
个人中心,用户管理,文章分类管理,文章信息管理,资料分类管理,资料下载管理,问答管理,论坛交流,留言板管理,系统管理等。用户功能有个人中心,文章信息管理,资料下载管理,问答管理,我的收藏管理。因而具有一定的实用性。
本站是一个B/S模式系统,采用Spring Boot框架作为后台开发技术,前端框架是VUE,MYSQL数据库设计开发,充分保证系统的稳定性。系统具有界面清晰、操作简单,功能齐全的特点,使得知识管理系统管理工作系统化、规范化。
本系统是基于B/S架构的网站系统,设计的管理员功能结构图如下图所示:
本系统是基于B/S架构的网站系统,设计的用户功能结构图如下图所示:
用户可以在首页查看文章信息,也可以对文章信息进行收藏操作。界面如下图所示:
用户可以在论坛交流里面发布信息和查看信息,发布信息需要提前登录才可以操作。界面如下图所示:
知识管理系统的管理员可以对用户新增,修改,删除,查询操作。具体界面的展示如图
管理员登录可以在文章分类新增,修改,删除,查询资料分类。具体界面如图
