本论文的研究课题是陕西21世纪初高等教育教学改革工程项目(0204014),目标为构建网络化的积件组合平台,为我国第二代CAI教学课件建设提供技术支持。网络化远程教学环境是现代教学发展的方向,而基于积件(Integrable Ware)思想的组合平台逐渐成为教学上流工具。本文围绕组合平台系统实现以及运行环境的设计展开研究,主要研究工作包括以下儿个方面:
目前的积件系统人多是采用专用软件,将积件组合成固定不变的课件,层次性差、表现方式单一。本论文提出了利用元数据的概念使积件的组成可以随意组合和调整,并从数据类型和数据来源两方面扩大了积件库的资源范围。利用XML数据将表示和过程分离,对不同来源的数据进行集成的优势以及层次化的树形结构特点,采用XML文件的课件形式。达到了既体现课件的层次性,同时可以对任何一个层次的内容进行重组和再利用的效果。
在对多种数据管理进行比较后,确定对积件资源采用文件管理系统与关系数据库结合的方法,将多媒体文件本身以文件系统的方式存储,用关系数据库管理其说明。利用文件系统在存储方面的优势,结合关系数据库较强的查询能力。在查询速度和文件管理两方面取得了最佳效果。
在研究了当前网络环境以及教学现状后,确定采用基于.NET技术的C/S和BlS相结合的混合结构,不仅保证网络化积件平台的可用性,同时在非网络化条件下,可以将组合平台作为一个独立的课件编写和演示工具使用。
Microsoft.NET被称作“下一代视窗服务,=NGWS倒ext Generation Web Service)o采用Microsoft .NET作为开发平台,C#.NET作为组合平台开发语言,.NET开发环境对XML提供专门的接口,利用C#允许XML数据直接映射为结构数据类型以代替类的特点,提高了系统灵活性。
在平台网络环境的构建中,服务器端采用Helix Server提供网络视频数据流服务。同时
采用MDS加密技术、权限管理、开放端口限制等多种方法维护系统的安全.
