在线考试系统文献综述中文摘要:随着网络技术的日益成熟,网络已经深入到生活的每一个角落,包括教育、购物、咨询、办公等等许多领域。
在网络迅速发展的今天,网页技术的应用也越来越广泛。
网页技术的应用对于教育行业来说优势更加的明显。
教育行业可以通过网络进行学生和教职工的管理、组织学生在线考试、在网站上发布学校相关信息等活动。
这样不仅能增加学校管理的透明度,还提高了学校的管理水平。
在线考试还能充分的利用学校的现有资源,大大减轻教师的工作量,把老师从出卷、阅卷等一些繁重中做中解脱出来。
本文重点论述了由于网络的存在扩大了学校的服务范围,为学校的管理提供了更多的条件。
对此做出了详细的调查,可行性研究和分析。
系统采用了B/S结构,在网络上建立学校自己的教育网站。
系统开发经历了系统分析、系统设计和系统实施三个阶段。
从设计方案的提出,经过详细的调查,分析了方案的可行性和必要性,通过详细的系统设计,力图提高系统的集成性和快捷性;
并在系统实施阶段收集了大量的实验数据,以便测试阶段系统的准确性和稳定性。
系统整体是基于浏览器/服务器,前台应用JSP技术,后台采用SQLServer2000作为数据库与前台连接。

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
