【摘要】 随着计算机网络技术的发展和高校教务制度的改革,建立功能完善、性能良好的综合教务系统管理平台是高校管理工作不可缺少的一项重要工程。本文通过对高校教务管理系统现状及难点的分析,提出了基于数据挖掘和J2EE架构技术结合的设计思路,并开发了一个高校综合教务管理系统。 针对具体的教务管理模式,结合某高校教学管理的现状,设计并开发了基于校园网的综合教务管理系统,采用Browser/Server模式的三层体系架构,为大专院校教务管理部门实现科学教学管理提供了一套功能完善、蕴涵先进的管理思想的综合教务信息系统解决方案。 本文首先分析教务管理系统的特征,划分教务管理系统功能,从系统总体架构和系统技术架构两个方面进行了系统的设计。 然后以排课子系统、选修子系统为基本模型,从系统体系结构、数据库设计、分类规则挖掘和算法设计与实现等诸多方面阐述了系统的实现方案。 本系统的主要特点体现在以下几点: 1、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,对高校教务系统的框架采用MVC模式的方式设计,并用struts技术来表现。 2、综合教务系统中的数据挖掘手段 基于分类决策树算法,建立了一个挖掘体系。针对排课和选课模块,分析影响学生学习效果的因素,为排课和选课过程中课程的选择提供决策分析思路。 3、基于优先级的排课算法 设计了资源归类基于优先级的最佳调度算法,依据分类规则,排出资源合理匹配、学习效果最优的课表。更多还原

【Abstract】 With the development of computer network and the reformation of the high educational administration system, it is absolutely necessarily to build a perfect, intelligent educational administration system. Based on the discussion about the situation of current high educational systems and the difficulty to build these systems, this thesis proposed a new design of high educational system that is based on data mining and J2EE structure, and developed a integrated educational administration system.According to the educational administration pattern and the situation of educational administration in our university, we designed and developed a educational administration that is based on the campus network. This system is designed in the 3-tire Browser/Server model, and provides a perfect integrated educational administration system for educational administration sections, with advanced administrational theory and various functions.This thesis firstly analyses the features and functions of educational administration systems; and then, this thesis discusses the structure of the whole system systemically and technically.And then, taking course scheduling sub-system as example, the structure of the sub-system, the database design, classification rule mining algorithm, and the development of the sub-system is introduced dentally. The following is the main feature of this system:1, System Structure Based on J2EEVarious J2EE core designing theories are applied in the development of the system, with MVC design pattern being applied to the structure of high educational administration system, and being realized by STRUCTS technology.2, Data Mining for Integrated Intelligent Educational Administration SystemFor course scheduling sub-system, the factor that affects the studying of students is analysed, which provide useful guide for decision-making. An intelligent mining system is created based on the decision tree algorithm.3, Course scheduling Algorithm Based on PriorityA prime schedule algorithm, which is based on priority, is designed. According to the classification rules, it can make best schedule which make best utilization of resource, and can generate the best studying performance.更多还原
