【摘要】 在当今知识爆炸的大背景下,运用B/S体系架构结合动态网页设计技术和新兴的多媒体技术,来设计远程学习考试系统成为了一个热门课题。各类院校和远程教育机构都特别开设了此类系统来应对当今的社会发展要求。而目前,我公安战线普遍警力不足,工作繁忙,很难集中进行学习。再加上各警种涉及的学科知识不同,学习的内容多种多样,因此集中学习的模式很难适应现代学习的需要。同时,很难对民警的学习过程进行监控,也不可能组织各种考试检验学习效果,最终考核的依据也不确定,按传统教育方式,作业的布置、批改和统计较为困难,这样势必会造成民警的学习只是形式化,很难提高民警的各方面素质,也很难建设一支真正优秀的民警队伍。本论文集中在针对探讨警员如何在网上学习、考试的基础上来展开研究,并结合当前的流行的网络开发技术和软件工程方法提出一个集设计与实现于一体的网上警用学习考试系统平台模型。本文首先对目前流行的C/S和B/S两种架构进行了分析和比较,指出C/S架构的服务器参与了数据传输会导致在访问量增大时其成为系统的瓶颈,而B/S架构无论是在互联网上推广使用还是系统的更新维护等方面来说都是非常方便和低成本的。然后,本文系统地研究了当前流行的各种动态网页地设计方法,并讨论和选择了适合网上警校建设的开发语言和工具。本文利用ASP技术作为开发环境,ADO技术连接数据库,提出了在B/S架构上建立数据交换的平台模型。在程序的实现中,本文以扩展性、高效性、稳定性为目标,实现了教师授课、学生学习、学生考试和成绩查询等方面功能,使网络教学中教与学能紧密的结合,更好地增强学习效果,提高了网络教学的质量。本系统适用于各级教育机构或机关部门,达到即学即考即会即用的学习效果。更多还原

【Abstract】 In now under knowledge explosion big background, using B/S system construction union dynamic homepage design technique and emerging multimedia technologies, designed the long-distance study test system to become a popular topic. Each kind of colleges and universities and the distance learning organization specially open this kind of system to deal with the now social development request. At present, my public security police forces are universal insufficient, the work is busy, very difficult to concentrate carries on the study. In addition various police plant the discipline knowledge which involves to be different, the study content are many and varied, therefore massed learning’s pattern is very difficult to meet the modern study need. At the same time, carries on the monitoring very difficultly to police’s learning process, is also impossible to organize each kind of test examination study effect, inspects finally the basis is indefinite, according to the traditional education way, the work arrangement, revises with the statistics is more difficult, will create police’s study only will be the formalization like this inevitably, very difficult to improve police’s various aspects quality, also very difficult to construct a genuine outstanding police troop.How in this collection is aiming at discusses the police officer in on-line study, the thesis foundation to launch the research, and unifies the current popular network development technology and the software engineering method proposed that a collection design with realizes uses the study test system platform model in a body’s on-line police. This article first has carried on the analysis and the comparison to present popular C/S and the B/S two kind of constructions, pointed out that the C/S construction the server participated in the data transmission being able to cause when the visit quantity increased it became system’s bottleneck, but B/S construction, regardless of promoted aspects and so on use systematic renewal maintenance on the Internet is very convenient and the low cost. Then, this article has studied the current popular each dynamic homepage design method systematically, and discussed and chooses has suited on-line police school construction the development language and the tool. This article uses the ASP technology to take the development environment, the ADO technology connection database, proposed establishes the data exchange on the B/S construction the platform model. In procedure realization, this article take the extension, highly effective, the stability as a goal, realized the teacher to teach, the student to study, aspect functions and so on students test and result inquiry, caused in the network teaching to teach with study to be able the close union, strengthened the study effect well, improved the network teaching quality. This system is suitable for all levels of educational institution or the institution department, achieves study effect which namely study namely tests namely meets namely uses.更多还原
