期中考试题目：
校园社团活动管理系统（20分）
1、项目需求：
校园社团作为高校课外活动的重要组成部分，发展十分迅速，也受到越来越多学生的欢迎，社团规模、数量等都在日益增长，社团活动也更为多样和丰富。然而，大多数高校还没有一个完整成熟的社团管理系统，仅仅是靠人力来管理，导致效率低下，而学生也只能通过线下或者公众号的方式了解社团，另外，社团活动的通知方式也很杂乱，并没有一个信息聚合、消息发布的平台。
因此，高校有必要建立一个校园社团管理系统，使得社团管理工作规范化、系统化、程序化、科学化，提高管理工作的效率。
2.系统要求与功能设计
2.1 页面功能要求
（1）能够在Tomcat服务器中正确部署，并通过浏览器查看；（1分）
（2）网站页面整体风格统一；
图1 活动普查系统功能结构图
（3）主页面：要求显示发布活动信息、修改活动信息、删除活动信息、查询活动信息，活动信息浏览五个子菜单。（1分）
（4）发布活动信息页面：（6分）
①完成添加活动信息发布，基本信息和填报限制如下表所示
|
活动主题 |
字符串（不超过20个汉字） |
|
活动目的 |
字符串（不超过50个汉字） |
|
活动类型 |
社团竞赛、野外采风、校内集会、社团纳新（单选框） |
|
活动时间 |

在本次的期中考试中，我基本完成了系统所需要求，但是系统仍有很大缺陷，例如虽然做了活动若有多项重复内容时不可录入的判断操作，但如果录入多个主题相同但内容，时间地点等不同的活动后在进行删除操作时会删除所有主题相同活动，对于这一点，我会在往后的学习中积极加以改进。
