离散数学教学网站设计（毕业论文）.doc

摘    要

本文就离散数学这一门学科提出了教学管理网络化系统的设计思路、开发步骤、工作流程、体系结构与功能，并对大学教学管理网络化系统的可拓展性进行了分析。教学管理网络化是当今国际教学管理信息化的主要趋势,以多媒体计算机技术和网络通信技术为主要标志的信息技术，作为现代科技革命的基础和核心，已经渗透到社会的各个领域，影响和改变着我们的工作方式、学习方式和生活方式乃至思维方式，也将会大大促进人类社会的发展和进步，而且也必将引起教学管理领域的深刻变革，使教学管理的体制、教学管理内容、教学管理方法、教学管理模式、教学管理思想和教学管理观念等产生新的重大飞跃。教学管理网络化所具备的“教学管理资源共享、信息交流”等功能，打破了传统教学管理在时间和空间上所受的限制，它能使分布在大学不同的学科、不同的时间、不同的地方都能得到丰富的教学管理信息，能使每一个教师和学生受益。

本文首先介绍了离散数学教学管理的现状及开发背景，然后论述了系统的设计目标，系统需求和总体设计方案，较详细的论述了系统的详细设计和实现。最后，本文对离散数学教学管理网站系统进行了系统检测并提出了还需要改进的问题。

本论文的设计任务是以实际应用为开发背景，运用软件工程管理和开发方法，采用当前网络开发主流技术，结合JSP和MySQL数据库技术，设计并开发的一个基于B/S模式的教学管理系统。首先对开发系统进行了需求分析，得到了功能需求，数据流图和数据字典。随后对系统进行了概要设计和详细设计，在概要设计中将系统划分为教师登陆模块和学生登陆模块，注册模块，资料上传，问题提出和回答模块，整个系统基于MVC架构通过Spring+Struts2.0+Hibernate3.0来实现。

关键词：B/S模式；JSP；MySQL；MVC

Abstract

    The thesis advances designing concept, developmenting process, working flow, system structure and function of the teaching network management system that bases on Discrete Mathematics , and university teaching network management system scalability are analyzed. By means of Internet and Multimedia technology disseminating knowledge,it is an  important research topic in the new situation for the institutions and universities to adapt to social development ,change the concept of teaching and carry out education innovation.it will not only  promote the development and  human society greatly, but also will lead to profound changes in teaching management, teaching management system and the content of teaching management, and the teaching management concepts will creat new and major leaps. Teaching Management Network have the function that is "teaching management resource sharing, information exchange", it throw convention to the traditional teaching management at the  time and space. We can get the teaching management information on anywhere and at any time, it greatly helps teaching work. 

    The thesis has firstly introduced the practical situation and the developing background of the system. And then has described the designing goal、system need and the whole designing plan, has described the detailed design and reality of the system in detail. Finally, conclusion has been drawn about the system and problem has also been raised.

    The task of the thesis is a teaching management system that based on practical application of web development background, used software engineering management and development methods,combined with JSP, and SQL database technology, designed and developed on B / S mode.Firstly, the author worked on the Requirement Analysis,and got the functional requirement,data flow diagrams and data dictionary. Then I got the system designand the implement, this system is divided into 4 modules ,that is loginned by teachers and loginned by students , register,data upload, the question and answer module, all the system is based on MVC architecture which is achieved by Spring + Struts2. 0 + Hibernate3.0 .  

Keywords：B/S model；JSP；MySQL；MVC
