【摘要】 教育资源素材库建设是现代远程教育工程的重要组成部分，并作为国家基础性设施来组织建设。教学素材库的内容应按学科、专业和行业进行组织，按照其素材的表现形式，可分为微小课件素材库、案例素材库、试题素材库和媒体素材库等。 教学素材库建设是一项极其庞大而复杂的工程，涉及到许多理论和技术问题。本文主要就教学素材库结构设计作初步的研究和探讨。 本文首先阐述了教学素材库在现代远程教育中的重要地位和作用以及它与网络教育资源间的相互关系，并通过讨论网络课件的发展过程和未来的发展方向说明了素材库建设的必要性，同时探讨了素材库建设的内容。 然后，本文对教学素材库的结构设计进行了分析和探讨，提出了一个三层体系结构的素材库模型：自底向上分别为管理层、查询层和应用层。其中，对管理层构架中的素材库组织结构进行了较深入的分析、讨论。 本文在研究了远程数据访问技术CGI、API、IDC、ASP、JDBC和TRS的基础上，提出了利用TRS全文信息管理系统和关系数据库的集成系统，即TRS forRDBMS Gateway系统作为网络资源素材库数据库平台的建设方案。在构建庞大的素材库系统时，通过TRS for RDBMS Gateway系统，就可以对存储在素材库中的海量结构化和非结构化数据进行高效、安全和可靠的发布和增值利用，实现数据的有效管理、查询和生成等诸多功能。更多还原

【Abstract】 As an important component part of the modern distance education project, the material library of education resources is organized and built in the form of national fundamental facility. The content of this library, organized according to subject, specialty and profession, can be classified by function into mini梒ourseware material, example material, examination material and media material.It is a very large and complicated project to build a material library of education resources, which would involve a lot of theoretical and technical problems. Mainly, this thesis makes some preliminary study and discussion on the structure design of the material library.The paper firstly discusses the library抯 important role in the modern distance education and its relationship with the education networkresources. It also shows us the necessity of building the library bypstudying the past and the future about the development of the networkcourseware, and something concerning how to make up the content of the material library.Secondly, analyzing the structure of the material library of education resources, the thesis gives to the material library an idea of building a framework model with a three條ayer system which contains management layer, inquiry layer and application layer from bottom to top. Among the three layers, the thesis does some further analysis especially to the library structure of the management layer.IIEventually, on the basis of carefully studying on the distance database access technology such as CGI, API, IDC, ASP, JDBC and TRS, the thesis designs the scheme of which to build the platform of the network material library utilizing TRS for RDBMS Gateway. On account of the necessity for building the large library to achieve successful management, inquiry and application about data, by the means of integrating TRS information management system and RDBMS, we can make efficient, safe, reliable issues and value梚ncreased utilizations of massive structuralized and unstructuralized data being stored in RDBMS.更多还原
