摘要
基于HTML开发的专题学习网站,在标准化、交互性、可移植方面存在种种不足;而XML技术以开放的方式结构化地表述数据信息,具有处理过程和数据分离、更精确的搜索、数据存储更灵活等优势,不失为解决上述问题的有效方法.文章对专题学习网站的结构进行分析和探讨,利用XML相关技术,结合知识树型结构与知识点的特性,构建了一种基于XML的三层数据交换体系结构,并阐述了网站主要功能模块的实现.该系统具有操作简单、查询方便等特点,便于实现教学资源共享,提高素材资源的利用率,能更好地协助学生自主学习.
A special subject learning website based on HTML is not standardized or transplantable,and is difficult to exchange data with each other. The XML technology now becomes an effective way to this problem because it defines data in an open and structural mode. It has many advantages such as the divorce of data and form of expression, more exact search, and more flexibility on data store. This article analyzes the structure of the special subject learning website,fixing eyes upon the tree-structure of learning sources, the characteristics of knowledge point. The XML and its relevant technology are used to establish a framework model with a three-layer based on XML, and some of them are realized. This manipulations and quick search. It's easy to share resources and improve the efficiency of media material independent learning. system for the special subject learning website system has a lot of advantages such as easy the media material among much educational utilization.
