前言：

为方便各高校对在校园内举办的各类竞赛进行有效的管理，我设计了这套基于SSM实现的竞赛管理系统。我所设计的这套竞赛管理系统，就是基于这样一个时代背景应运而且，一是可以大大降低各高校对于校内所举办的各项竞赛管理的各项成本；二是可以大大提高各类竞赛信息管理的效率。使用计算机对竞赛进行管理的优点如：检索迅速、查找方便、易修改、存储量大、保密性好、成本低等。因此，建立一个规范、合理、实用、有效的竞赛管理系统对竞赛资料进行集中统一的管理就显得格外重要。目前来看，在政府、工商业、学校、企事业单位等单位中，每年都会举办一些各式各样的竞赛活动，几乎都会应用竞赛管理系统进行信息化管理。通过信息化的手段在竞赛管理中加入计算机软件的应用，本质上其实就是对于竞赛相关信息进行管理。利用管理信息系统对竞赛馆的竞赛进行有效的管理，可以大大提高竞赛管理竞赛管理的效率，提升使用的方便性以及其安全性。

本竞赛管理系统本质上利用了信息管理系统的基本思想，综合应用了基于软件开发JAVA相关技术，并以关系型数据库MYSQL作为数据存储的基本手段，主要实现了竞赛管理员对竞赛活动、竞赛作品、以及参赛用户信息和相关评委信息进行存储和管理，并实现了对相关信息基本的增、删、改、查的基本操作功能，这样就可以很好的提升竞赛相关信息的管理质量，提升系统参与的用户的体验感。

一，项目简介

竞赛管理系统的使用者主要包含三种用户角色，其一是管理员角色，其二是参赛用户角色，其三是竞赛评委角色，评委可以指定教师或外部工程师。这三个角色的具体功能如下：

管理员角色：管理员登录竞赛管理系统后可以进行相应的管理操作，主要包含：学生用户管理、竞赛活动管理、老师管理、工程师管理、个人信息管理、账户密码重置等操作。

参赛用户角色：参赛用户登录竞赛管理系统后可以进行参与相关竞赛、提交和下载个人竞赛作品、个人信息管理等操作。

评委用户角色：竞赛中指定的活动评委，可以登陆系统对担任评委的竞赛活动的作品进行评分操作。

根据上述对系统的功能性需求分析，设计出了竞赛管理系统的功能结构图，如下图3-1所示：

图3-1 系统功能结构图

系统简单性原则：系统操作界面应尽量简单易行，让非专业的系统使用者能够快速上手，符合用户常用的操作习惯，不要设计过多复杂的操作。

系统针对性原则：通过对高校竞赛管理人员日常参与竞赛管理的基本流程的调查研究，开发并设计了竞赛管理系统，所以本系统面向的主要是竞赛参与的相关人员。另外就是针对竞赛的管理用户使用，让他们能够方便的进行竞赛评分和人员管理操作，并方便的进行相关信息的查询。

系统实用性原则：竞赛系统所具有的功能都是与竞赛活动有关，对竞赛活的管理者和参赛用户都具有一定的帮助性和实用性。

系统一致性原则：竞赛系统页面的设计采用了统一的风格，操作规则也进行了统一，数据显示也大致相同的，对于系统管理者和前端用户的操作均简单易懂。

系统先进性原则：本系统采用了SSM框架，JSP技术、Mysql数据库，这些都是目前企业开发中使用较多的开发技术和数据库服务器，并且使用了B/S架构模式和三层结构设计，这就使竞赛管理系统具有良好的可扩展性和灵活性。

五，项目总结

当今社会，各种竞赛、比赛到处比比皆是，小到幼儿园，大到大学生，学生阶段应该是参与相关竞赛最多的群体。可以通过竞赛去选拔人类中的佼佼者，给一些优秀人更好的发展机会和更多的鼓励。而对竞赛的相关数据和信息管理在以往一直是以传统的手工或纸质方式来进行处理，效率低下而又极易出错。在当今的互联网时代，如何使用IT信息化技术对竞赛的相关活动和数据进行处理，提高工作效率和降低出错率，是我们面临的一个急需解决的问题。

本项目主要基于SSM(Spring+Springmvc+Mybatis)三种开发框架开发而成，页面显示采用的是JSP技术，前端采用是BootStrap框架，数据库选用目前比较流行的关系型数据库 MYSQL数据库。系统设计基于B/S架构，采用了瀑布式的的系统分析与设计方法，实现了一个用于学生竞赛活动管理的相关功能的管理系统，构建了一个方便对学生竞赛活动进行管理的学生竞赛活动管理系统。
