信息数据从传统到当代，是一直在变革当中，突如其来的互联网让传统的信息管理看到了革命性的曙光，因为传统信息管理从时效性，还是安全性，还是可操作性等各个方面来讲，遇到了互联网时代才发现能补上自古以来的短板，有效的提升管理的效率和业务水平。传统的管理模式，时间越久管理的内容越多，也需要更多的人来对数据进行整理，并且数据的汇总查询方面效率也是极其的低下，并且数据安全方面永远不会保证安全性能。结合数据内容管理的种种缺点，在互联网时代都可以得到有效的补充。结合先进的互联网技术，开发符合需求的软件，让数据内容管理不管是从录入的及时性，查看的及时性还是汇总分析的及时性，都能让正确率达到最高，管理更加的科学和便捷。本次开发的校园新闻管理系统实现了字典管理、论坛交流管理、公告信息管理、新闻管理、新闻收藏管理、新闻留言管理、用户管理、管理员管理等功能。系统用到了关系型数据库中王者MySql作为系统的数据库，有效的对数据进行安全的存储，有效的备份，对数据可靠性方面得到了保证。并且程序也具备程序需求的所有功能，使得操作性还是安全性都大大提高，让校园新闻管理系统更能从理念走到现实，确确实实的让人们提升信息处理效率。

小康时代的到来，使得人们满意度上升，生活各个方面都产生了许多变化，比如办公都有相应软件，很多工作都要求员工会操作计算机，可以说现在的时代基本被软件覆盖得差不多了，软件行业的特征就是大家都在使用软件代替传统手工记载操作，软件的出现让我们的生活还有工作又向前翻了新篇章。校园新闻管理系统是一个利用软件形式管理新闻信息信息的平台。管理员管理租车信息也不再需要用纸张进行信息记录及查询管理操作，所有的操作都是利用电脑进行办公，用户需要使用密码还有用户名进行系统登录操作，按照系统主页界面的各个功能展示进行相关操作，无论添加或者是删除，拟或是修改查询等操作，时间上不需要太多，短短几分钟就会搞定。况且软件是不限制办公地点以及办公时间的，只要有操作需要，随时随地登录系统就可以完成任务。办公效率提高这个不再是难题。

本次开发的校园新闻管理系统的论文从下面几个部分进行编写：

第一章：本章介绍了程序开发背景和目的意义，罗列出了论文写作内容信息，让我们知道论文编写是如何进展的。

第二章：本章主要讲解了系统开发用到的相关技术方面的知识，比如springboot技术，MySQL数据库知识等内容。帮助人们更好的理解系统技术上面的相关知识。

第三章：文章第3章主要介绍了系统开发的可行性问题，从经济，时间，操作等内容上面进行了大致介绍，确定系统开发确实可行，然后分析了系统的开发流程，确定系统需要具备的大概的功能，保障系统能够稳定使用和运行。

第四章：这个章节主要绘制出了系统功能架构，让我们更直观了解校园新闻管理系统的功能，对后台数据库表进行了设计，还画出了对应的Ｅ－Ｒ图。

第五章：这个章节主要介绍系统各个部分功能具体实现的界面效果。让我们了解到各个部分的功能详细情况。

第六章：这个部分主要就是对校园新闻管理系统进行整体测试，看看程序是否能够达到用户使用要求，程序能否进行验收上交操作。
