【摘要】 《军事训练多媒体网络教学系统》是由总参军训部主持的重点科研项目,其目的是依托校园网与军训网,以分布全军的多媒体资源为基础,为全军院校的现代化教学提供一个统一、规范的网上平台。 本文提出了系统体系结构和计算模式;提出了军训网和局域网中的系统模型;提出了根据不同功能分别应用C/S、B/S模式的实现策略。 本文分析了Microsoft.NET的体系结构、Web Service及XML数据访问机制等技术,这些技术是系统实现的重要技术基础。 最后,本文详细介绍了全网资源搜索引擎的设计与实现(包括远程数据访问、简化的多对多数据访问模式、大结果集的处理与检索结果本地化处理、动态更新站点在线状态等),大对象的缓存,客户端脚本开发,以及如何结合ASP.NET与NetMeeting实现在线实时教学。

【Abstract】 Multimedia e-Learning System for Military Training" is sponsored by PLA General Staff. The system works on Campus-Net and Military-Training Net and it makes use of multimedia resources in Military-Training Net to provide a normal and uniform platform for modernization teaching & learning.This paper presents the system architecture and computation schema. The paper brings the system models in Military-Training-Net and Campus-Net as well as different Networking Application Modes according to system functions.The paper analyzes the architecture of Microsoft .Net and mechanism of XML Data access and technology of Web Service which build the theoretical foundation of the system .Finally, the paper introduces the design and realization of resource search engine(including remote data access, simple mode of multi-multi data access, handling of large Result-Set, native operation of searching result, dynamitic updating online status), large object caching, development of Client-side scripts as well as ASP.NET and NetMeeting based implementation of online Real-time Teaching & Learning.
