一.前言介绍
毕业设计是本科教育的最后一个环节，整个过程包括课题拟定与审核、师生双选、开题报告、文档审核、中期检查、毕业答辩等多个环节，是一项系统而复杂的工作。开发一个适合本校的毕业设计管理系统，不仅能够极大地减少教务管理人员的工作量，还能较大地提高学生和教师的效率。
二、主要技术
2.1 SSM框架介绍
本课题程序开发使用到的框架技术，名称缩写是SSM，在JavaWeb开发中使用的流行框架有SSH、SSM、SpringMVC等，作为一个课题程序采用SSH框架也可以，SSM框架也可以，SpringMVC也可以。SSH框架是属于重量级别的框架，配置繁琐，不够灵活，修改程序需要修改好多个文件，并且运行起来也占用内存较高，CPU使用率相对也高，SpringMVC是Spring开发的一套MVC架构，更灵活更好用，SSM框架取中间值，既没有SSH臃肿，也没有SpringMVC简化，属于中间级别的，在配置过程和使用过程中更能编写和理解。MyBatis框架取代Hibernate框架是因为它更灵活，不需要完全在框架里操作，它在数据操作上可以写出更灵活的代码，它的性能也比Hibernate框架更稳定。总的来说，使用SSM框架是通过综合考虑而使用的，网上有很多的使用教程和心得体会，而且SSM又是这么的流行，用SSM框架开发是顺其自然的。
2.2 MYSQL数据库
Mysql的语言是非结构化的，用户可以在数据上进行工作。MySQL因为其速度、可靠性和适应性而备受关注。大多数人都认为在不需要事务化处理的情况下，MySQL是管理内容最好的选择。并且因为Mysql的语言和结构比较简单，但是功能和存储信息量很强大，所以得到了普遍的应用。Mysql数据库在编程过程中的作用是很广泛的，为用户进行数据查询带来了方便。Mysql数据库的应用因其灵活性强，功能强大，所以在实现某功能时只需要一小段代码，而不像其他程序需要编写大段代码。总体来说，Mysql数据库的语言相对要简洁很多。
2.3 持久层框架MyBatis
MyBatis 是一款优秀的持久层框架，它支持定制化 SQL、存储过程以及高级映射。MyBatis 避免了几乎所有的 JDBC 代码和手动设置参数以及获取结果集。MyBatis 可以使用简单的 XML 或注解来配置和映射原生信息，将接口和 Java 的 POJOs(Plain Ordinary Java Object,普通的 Java对象)映射成数据库中的记录。
2.4 前端框架BootStrap
Bootstrap是美国Twitter公司的设计师Mark Otto和Jacob Thornton合作基于HTML、CSS、JavaScript 开发的简洁、直观、强悍的前端开发框架，使得 Web 开发更加快捷。
Bootstrap中包含了丰富的Web组件，根据这些组件，可以快速的搭建一个漂亮、功能完备的网站，其中包括以下组件：下拉菜单、按钮组、按钮下拉菜单、导航、导航条、路径导航、分页、排版、缩略图、警告对话框、进度条、媒体对象等。
三. 系统设计
3.1 系统架构设计
系统的组织架构如图所示，三种用户根据自己不同的权限对课题、文档、成绩、公告、任务五种数据信息进行处理，不同用户角色再根据这些数据信息进行交互通过课题进行交互，并且围绕着文档进行数据的传递和处理等。
本系统依据学生、导师、管理员三种不同用户角色的需求，分为了三个大的功能模块，三种用户角色在各自的模块进行操作，可以通过课题进行与其他两种用户角色之间的交互，并且围绕着文档进行各种数据（用户信息、文档信息、课题信息）的传递和处理等，这就形成了系统的体系结构，管理员发布课题给学生，学生选择课题呈现给导师，导师自拟课题向管理员申报，如图所示。
同时三种用户可对五种数据信息进行不同的处理（增删查改的权限不同），表现在系统上就是拥有不同的功能模块，所以分为三个大的模块，每个模块有相应的小的功能模块，系统的功能结构如图。
3.2 系统功能模块
本系统包含三种用户：学生、教师和管理员。通过本系统，学生可以获取指导教师和管理员发布的相关教学信息和教学资源；教师可以进行毕设进度的日常管理，发布任务、上传资料、审核文档等；管理员可以进行系统的管理和维护，并对教师、学生、课题和文档进行管理，确保系统的正常运行。系统总共分为3个模块。
3.2.1 学生模块
学生登录系统后进入该模块，在该模块中，学生能够修改个人资料和登录密码，选择感兴趣的课题及导师，下载导师上传的相关参考资料，上传自己已经完成的文档，查看发布的公告、任务和自己的阶段成绩等。
3.2.2 教师模块
教师登录系统后进入该模块，在该模块中，教师能够修改个人资料和登录密码，选择学生，上传拟好的课题题目给管理员审核，发布阶段任务，上传相关资料给学生参考，下载学生上传的阶段文档并审核和打分，查看公告及发布新公告等。
3.2.3 管理员模块
管理员登录系统后进入该模块，在该模块中，管理员可以增删查改导师和学生的信息，审核教师上传的课题，发布公告，查看各种信息，查看各种数据分析的结果和图表。
四、数据库设计
4.1 数据分析
本系统的主要数据表为存储学生、教师、文档、课题数据集的四个表。其余表大多作为外键关联用于完善四张表的信息。
4.2 概念设计
数据库主要围绕学生、教师、 课题、文档4个实体进行数据处理。即系统只要处理好这4个实体的数据，就可以完成系统的绝大部分功能并让毕业设计管理的整个流程顺利进行下去。其余的数据表则是围绕这4个实体相应展开，进行一些扩展和补充，以完善整个数据库的结构并加快数据库对请求的响应速度。
4.3 重要E-R图
4.3.1 数据库文档处理的E-R图
4.3.2 数据库文档处理的E-R图
4.4 表设计
数据库中一共设计了15张表，和学生相关的表有6张（包括学生信息、开题报告、文档成绩、毕设进度、学生疑问等），和教师相关的表有4张（包括教师信息、任务书、阶段任务、课题申报等），文档有1张表，课题涉及2张表，还有2张表属于公共信息表，用于进行一些补充以完善数据库。数据库的表清单如下表。
| 序号 | 物理表名 | 中文名称 |
|---|---|---|
| 1 | t_announcement | 公告表 |
| 2 | t_department | 学院表 |
| 3 | t_doubt | 疑问表 |
| 4 | t_major | 专业表 |
| 5 | t_student | 学生表 |
| 6 | t_student_opening_report_task_book | 学生开题报告表 |
| 7 | t_student_progress | 学生进度通知填写表 |
| 8 | t_student_score | 学生成绩表 |
| 9 | t_teacher | 教师表 |
| 10 | t_teacher_opening_report_task_book | 教师开题报告表 |
| 11 | t_teacher_progress_notification | 教师阶段任务表 |
| 12 | t_thesis_information | 文档提交表 |
| 13 | t_thesis_title | 教师提交课题表 |
| 14 | t_topic | 选题信息表 |
| 15 | t_user | 用户表 |

七. 项目总结
通过对毕业设计管理系统的开发，让我深刻明白开发一个程序软件需要经历的流程，当确定要开发一个系统的时候，对其功能进行合理的需求分析，然后才是程序软件的功能的框架设计，数据库的实体与数据表设计，程序软件的功能详细界面实现，以及程序的功能测试等进行全方位的细致考虑，虽然在此过程中，各个环节都遇到了大大小小的困难，但是通过对这些问题进行反复的分析，深入的思考，借助各种相关文献资料提供的方法与解决思路成功解决面临的各个问题，最后成功的让系统得以正常运行。商毕业设计管理系统在功能上面是基本可以满足用户对系统的操作，但是这个程序软件也有许多方面是不足的，因此，在下一个时间阶段，有几点需要改进的地方需要提出来，它们分别是：
（1）操作页面可以满足用户简易操作的要求，但是在页面多样化设计层面上需要把一些比较丰富的设计结构考虑进来。
（2）程序软件的总体安全性能需要优化，例如程序的退出安全性，以及程序的并发性等问题都需要进行安全性升级。
（3）需要对程序的数据结构方面，程序的代码方面等进行优化，让运行起来的程序可以保持稳定运行，也让程序能够保证短时间内处理相关事务，节省处理事务的时间，提高事务处理的效率，同时对服务器上资源占用的比例进行降低。
