基于UML的武警院校课件点播系统的设计与实现
摘要
本文针对武警院校信息化建设和自身发展的客观需要,研究在校内建立的多媒体课件点播系统。其意义在于:提高武警院校的课件管理水平,规范武警教官课件制作,方便武警学员查询资料、在线浏览课件,更好地发挥武警院校校园网的教学辅助作用。
本文先阐述了武警院校的教学特点、武警院校多媒体课件使用的现状,以及课题的选题背景和意义,然后对开发基于UML的武警院校课件点播系统进行可行性分析,接着阐述了系统中用到的关键理论与技术,随后提出系统的总体设计方案。在系统建模过程中,首先进行需求分析,定义用例来描述系统的主要功能,确定了系统的功能需求,由用例图来详尽地表示系统的各种关系。其次进行的是设计,包括架构设计和详细设计。在这部分中,定义包、描述包间的相关性和基本的通信机制。
武警院校课件点播系统按照最初的设想,基于UML进行设计与实现,搭建了服务器系统、客户端系统,文中给出了系统的总体构架结构图、主要功能模块和部分代码。系统的运行基本达到了预期效果,具有界面简洁明快、较为安全可靠、利于投入实用的特点。
For the Informational Construction and self-developing of the CAPF colleges, we studied how to create Multimedia Courseware Ordering System. The creation of this system will make great use of improving the CAPF colleges' level of managing courseware, making criterion of courseware designing, being easy for the students to check the data and learn the courseware, and advancing the education quality.
In this dissertation, it is introduced for the status of using multimedia courseware ordering system and the background and the significance of the Subject. Then we bring forward the feasibility analysis of the system; bring forward the collectivity project designing of the system. The system is separated into three subsystems, which are Managing Subsystem, Server Subsystem and Ordering Subsystem. Also we introduced the theory of realtimestreaming media technology; elaborate the organization of hardware and software of multimedia online broadcasting system nowadays.
The Courseware Ordering System of the CAPF Colleges according to the initial assume, designing and realizing on account of UML. In the main, the system finally comes to its expectation. The interface is succinct, the system is safe and it is easy to use.It is introduced that the achievement of the system, including the construction of the Server System and the Client System. In the main, the system finally comes to its expectation.
