1、项目介绍及开发技术

1.1 项目介绍

传统办法管理信息首先需要花费的时间比较多，其次数据出错率比较高，而且对错误的数据进行更改也比较困难，最后，检索数据费事费力。因此，在计算机上安装大学生平时成绩量化管理系统软件来发挥其高效地信息处理的作用，可以规范信息管理流程，让管理工作可以系统化和程序化，同时，大学生平时成绩量化管理系统的有效运用可以帮助管理人员准确快速地处理信息。

大学生平时成绩量化管理系统在对开发工具的选择上也很慎重，为了便于开发实现，选择的开发工具为Eclipse，选择的数据库工具为Mysql。以此搭建开发环境实现大学生平时成绩量化管理系统的功能。其中管理员管理用户，新闻公告。

大学生平时成绩量化管理系统是一款运用软件开发技术设计实现的应用系统，在信息处理上可以达到快速的目的，不管是针对数据添加，数据维护和统计，以及数据查询等处理要求，大学生平时成绩量化管理系统都可以轻松应对。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

2、系统功能设计结构图

3、功能截图

学生管理：学生的查询管理，可以删除学生、修改学生、新增学生，还进行了对用户名称的模糊查询的条件。

成绩信息管理 ：查看已发布的成绩信息数据，修改成绩信息，成绩信息作废，即可删除，还进行了对成绩信息名称的模糊查询 成绩信息信息的类型查询等等一些条件。

公告类型管理： 根据公告类型进行条件查询，还可以对公告类型进行新增、修改、查询操作等等。

公告信息管理： 根据公告信息进行新增、修改、查询操作等等。

4、数据库表结构设计
