1、摘摘 要要 本文分析了国内外网络教学应用的实际情况， 认为目前我国网上教学应用虽然取 得了一定的发展，但在技术实现、设计思路、系统实现等方面仍存在着一些问题，这 些从不同角度影响了网上教学的质量和效率。基于以上的认识，文章在对网上教学系 统建设需求进行分析的基础上，研究了目前较为流行的几种实现技术，论述了一个以 Struts 技术为主的网上教学应用系统实例的构建过程。Struts 技术作为目前企业或 商务开发中较为流行的一种软件开发技术标准，不但继承了 JAVA 的技术优点，而且 在软件的部署、扩展、管理等方面所采用了更为先进的实现理念。因此，作为一种尝 试，本系统在开发中引用了 Struts
2、 的技术构架。本文通过网上教学系统这一实例的 设计与实现，具体阐述了如何采用 J2EE 技术构架系统，如何设计系统数据库结构， 以及如何最终设计实现系统的功能模块。最后总结了目前网上教学中的缺陷与不足， 并对其发展提出了一些建议与期望。 关键词关键词：网上教学系统；J2EE；软件项目管理；Struts；功能模块 1 Abstract This paper analyses the real practicality of the E-Learning application in and out of the country. It puts forword that there has be
3、en great progress in our country, but there exists lots of shortage at the aspects of implement of technology, thoughts of management, realization of system. These impact the quality and efficiency of the E-Learning in different points of view. This paper, on the basis of the analysis of NTLS requir
4、ements, and of the study of the popular technology to realize the similar systems, discusses the realization of NTLS based on J2EE. J2EE is considered as a popular kind of the technique standard of the software exploitation. It not only succeeds to all the virtue of JAVA, but it has more advanced id
5、ea at the aspects of the deployment, enlargement, and management of the software. Thus, J2EE will be quoted into the exploitation of the NTLS. And it also provides the important assurance for the system achievement ultimately.In this section about the design and realization of the system, this paper
6、 explains how to design the whole system takes the technology of J2EE and how to design the data construction and how to finally realize every function mode of the system. At last, this paper concludes the disadvantages of the NTLS, and gives some advises and respects.
