【摘要】 随着计算机技术与网络通讯技术在教育领域的发展,教育信息化的发展与研究逐渐被提上日程。我国对教育信息化的投入逐年倍增,经过数十年的发展,我国各层次教育信息化的发展均卓见成效。然而,国内针对教育信息化水平评估及未来发展预测等方面的研究甚少。为了更好地对教育信息化发展水平进行评估以及大体掌握国内各地基础教育、高等教育以及职业教育信息化发展现状,并对我国教育信息化发展方向及趋势进行科学地预测,教育部已将教育信息化发展专题研究列入重要课题。2011年3月教育部正式同意在华中师范大学国家数字化学习工程研究中心筹建“教育信息化战略研究基地(华中)”,该基地的成立标志着我国教育信息化正步入一个更高的平台,正式进入了规范化、专业化、制度化的阶段。本论文以此作为研究背景,着重于教育信息化数据库平台原型的设计与开发,目的在于建立一个集国内外教育信息化资讯发布、文献资料下载、基础数据可视化显示、教育信息化水平评估和教育信息化未来发展预测多种功能为一体的开放式平台,满足不同用户的需求。本论文主要从以下几方面展开研究:(1)教育信息化基础数据库平台需求分析。主要从教育信息化管理现状的问题分析、用户类别、功能性需求及非功能性需求进行分析,并结合需求进行平台的数据建模,最后对本平台设计与开发使用的关键技术进行简要介绍。(2)教育信息化基础数据库平台设计。结合平台的各种需求,确定教育信息化数据库平台的总体解决方案,分别从体系架构设计、功能结构设计、数据库设计与界面设计多个角度论述平台的设计工作。(3)教育信息化基础数据库平台原型开发。主要介绍了平台基于B/S开发模式的三层技术架构,并分别从数据访问层、业务逻辑层和表示层展开论述,在表示层中展示了平台中部分主要模块的实现方法及实施效果。(4)教育信息基础数据库平台原型测试。主要从测试方法与内容、测试方案、测试用例设计与测试结果分析几方面展开。采用人工测试与工具测试相结合的方式对本平台的功能与性能进行测试。经过对本平台详细的需求分析与设计,平台原型基本功能已实现并通过了功能与性能测试。此平台的成功应用将为我国教育信息化的专题研究做出一定贡献。

【Abstract】 With the development of computer technology and network communication technology in the field of education, the development and research of e-education are gradually being put on the agenda. China’s investment in e-education is doubling every year, with the development in the past decades, e-education in China have achieved fruitful results at all levels. However, the research about the level assessment of e-education and its future development prediction is so little. In order to assess e-education development level better, to master basic education, higher education and vocational e-education present development situation of every area in China generally, to forecast the development direction and trend of e-education in China with science, e-education development has been established as an important subject by the Ministry of education. The "E-education Strategic Research Base (Central China)" in the National Engineering Research Center For e-Learning of Central China Normal University was formally agreed to establish by the Ministry of Education in March2011, which marks that the e-education in China has entered into a higher platform and the development of e-education is moving from the stage of "application" to the stage of "fusion" and "innovation", officially entering the stage of standardization, specialization, and institutionalization.Based on this background, the design and development of the e-education basic database platform is focused in this paper, aiming to establish an open platform combining a variety of functions including information dissemination about domestic and foreign e-education, documentation download, data visualization, automatic assessment and prediction of the level of e-education, meeting the needs of different users. The paper carried out the study from the following aspects:(1) Requirement analysis of the e-education basic database platform. This part mainly analyzed the status of e-education management, user categories, functional requirements and nonfunctional requirements, then constructed the data model according to the demands, finally briefly introduced the key technology used in the platform.(2) Design of the e-education basic database platform. This part determined the overall solutions of the e-education basic database platform combining with various needs, and discussed the design from several aspects, such as architecture design, functional structure design, database design and interface design.(3) The development of the e-education basic database platform prototype. This part mainly introduced the three-tier technical architecture based on the B/S model, discussing the development of the platform from the data access layer, business logic layer to the presentation layer, and displayed the implementation process and effect figures of the main modules of the platform in the presentation layer.(4) The testing of the e-education basic database platform prototype. This part mainly discussed the test method and contents, test plan, test case design and test results analysis. The functionality and performance testing were carried out with manual testing and tool testing.After the detailed requirement analysis and design, this platform prototype’s basic function has been realized and its function and performance testing were passed. The successful application of this platform will make a contribution for the study of e-education project in China.
