【摘要】 传统教务管理耗时和耗费，教务管理部门操作起来很烦琐，开发一种基于分布、网络计算的智能教务管理平台迫在眉睫。本次硕士论文设计的重点是在研究多种信息挖掘技术方法的基础上，通过对教务信息管理全过程各个环节的数据进行采集与分析，提出了结合数据挖掘和J2EE架构技术结合的设计思路，开发出适合我国国情的智能教务系统。 校园网的建立和Internet技术的引进为建立这样的系统提供了必要的条件。因此，我们针对具体的教务管理模式开发了基于校园网的教务管理系统。作者采用了B／S模式架构了网络体系，使用了目前流行的分布处理模式JAVA—EJB中间件的思想来进行信息挖掘。 在整个系统软件工程的实施中，作者使用了面向对象的分析、设计语言UML来进行分析和设计，完成系统静态和动态建模。已完成的教务系统可以提供智能化的挖掘分析功能，根据高校教务系统的基本数据，构建数据仓库，对学生选课、教师申请课程、审批流程、成绩管理等模块的状态进行跟踪，完成WEB上各个流程的分布处理。 本文混合运用数据挖掘的设计思想和J2EE的架构技术，结合UML进行分析与设计，具体工作包括： 1．用UML描述的基于WEB的高校教务系统原型 主要介绍了以UML为建模语言，以RUP为过程框架，开发基于J2EE的选课过程：使用例图、活动图来寻找用户需求，确立系统边界，从而建立系统的需求模型；构建分析类，使用分析类的顺序图、活动图、合作图来描述系统的分析模型；构件设计类，运用设计类顺序图、类图来实现系统的设计模型：使用构件图、配置图来描述系统的实现模型。论文中主要对选修课程、成绩管理做了重点描述。 2．基于J2EE模式的系统架构 在开发过程中广泛应用了多种J2EE的核心设计模式思想，结合系统框架和部署环境分别针对J2EE的网络层、EJB层和EIS层的不同情况制定了安全策略。 3．高校智能教务系统中的数据挖掘手段 针对教务系统中选课、课程申请模块对学生、教师的行为进行识别、分析和预测，为教务工作提供决策分析思路。因此，基于分类ID3决策树算法，作者建立了一个智能挖掘体系，并为开发其它数据挖掘应用系统提供了一个有价值的实例。更多还原

【Abstract】 The traditional education management makes waste of time and other teaching equipments. It is trivial for educational administration department to operate . Therefore it is very urgent for us to develop a sort of aptitude educational administration flat which bases on distribution and network calculation. The core of this thesis is represented with hereinafter items: On the base of studying many information exhumation techniques and through collecting and analyzing the data of each tache , the author put forward a design thought which combines data exhumation and build technology of J2EE ,and developed an intellectualized educational administration system that is suit for the situation of our country.The establish of campus network and the introduction of Internet technology provide indispensable conditions for building a system like this. Therefore, we developed an campus network based educational administration system which is dead against idiographic educational administration . The author adopted the B/S mode to build network system and used the current popular distributed disposal mode named JAVA-EJB middle-piece to make information exhumation.The author used the analysis of the orient-object and designing language UML to analyze ,design and complete system static-dynamic modeling. The completed educational administration system can provide intellectualized exhumation analysis functions. We can build data-base according to the datum of the higher school educational administration system. The data-base can tail after the module of course-choice for students, the module of course-application for teachers, the module of examining and approving flows and achievement-managing module to complete the distributed disposal of each flow on WEB.This text mixed design thought of data exhumation and J2EE building technology and combined UML to analyze and design. The concrete works contains:1. Basing on WEB higher school educational administration system described by UML It mainly introduced developing the choosing -course process which basing on J2EE and usedUML as modeling language,RUP as process frame: using example pictures , activity pictures to find user requirement, establishing system boundary and found the demand-model of system in the end ; to build analyzing species, using sequence chart.activity chart .cooperation chart of analysis species to describe the analysis-model of system : to build design species, using design species sequence charts ,species charts to realize design-model of system; using component charts .scheme charts to describe realization-model of system,, This thesis mainly described the elective-courses and achievement-management.2. System building basing on J2EE modelThe author broadly used kinds of core design model thoughts of J2EE in the developing courses. With combining system frame and disposing environment, the author constituted security policy in allusion to the different situations of J2EE’s network layer ,EJB layer and EIS layer.3. Data exhumation means in higher school intellectualized educational administration systemThe author provided decision-making analysis thought for educational administration work by using choosing-course and application-course models to recognize ,analyze and forecast the behavior of students and teachers. Therefore, the author established a intellectualized exhumation system basing on classification ID3 decision-making tree arithmetic, and provided a valuable example for developing other data exhumation applying system.更多还原
