【摘要】 智慧教育是一种全新的云服务模式。它可以有效地解决当前教育系统存在的信息孤岛，教学系统固化等问题，并为日益增长的教育需求提供支撑。智慧教育云平台的构建基于对大量教学活动相关数据资源的深度整合。这些数据资源存储总量巨大，不仅文件类型多样化，而且具有被大量用户频繁读取的特点。当今市场上还没有一款云存储系统提供针对智慧教育云平台的数据存储服务。常见的云存储系统支持的文件类型有限，不支持用户对私有数据资源进行服务接口级别的扩展，不能满足智慧教育云平台数据存储的需求。本文针对智慧教育构建了一种以计算资源公用设施化为基础的云存储系统。该云存储系统利用30台运行着64位版Windows Server2008R2系统的数据存储服务器实现了对智慧教育相关文本数据资源，图片数据资源，音频数据资源与视频数据资源的存储及管理，支持用户利用私有的数据资源快速地构建智慧教育云平台。云存储系统建立在由Hadoop组建的存储网络之上，利用Hadoop内部透明的数据管理机制保证了系统内数据资源的高可用性。本文通过对智慧教育相关数据资源的特点进行分析总结，在HBase中建立了可扩展的数据模型。云存储系统内所有的数据资源都会依据内建的数据模型存放在HBase中。云存储系统包括前台大容量在线存储系统与后台管理系统。用户通过前台大容量在线存储系统可以对智慧教育相关的数据资源进行上传，下载，管理等操作。系统管理员通过后台管理系统可以对云存储系统内的软硬件资源进行统一管理。针对智慧教育的云存储系统降低了智慧教育云平台的构建成本，其优质的数据存储服务不仅满足了智慧教育云平台当前海量数据资源的存储需求，而且支撑了智慧教育云平台后期存储需求的增长，保证了智慧教育云平台的高效运作。更多还原

【Abstract】 Wisdom education, as a new type of cloud service, can deal with the informationisolated island phenomena, solve the problems of solidification in the educationsystem effectively and provide support to increasing education demand. Theconstruction of wisdom education cloud platform is based on the deep integration ofvast relevant data about education activities with the characteristics of large storedquantity, various document types, and plentiful and repeated read. However, at present,there is no cloud storage system which provides data storage service to wisdomeducation cloud platform. The document type supported by the usual cloud storagesystem is limited which does not support users to expand private data source throughthe service interface, so it cannot satisfice the data storage needs of wisdom educationcloud platform.The present study constructs a cloud storage system based on the utilization ofcompute resource for the wisdom education. This cloud storage system realized thestorage and management of text data resources, picture data resource, audio dataresources, and video data resources of wisdom education by using30data storageservers with64-bit Windows Server2008R2operating system on it and realized therapid construction of wisdom education cloud platform by using private dataresources. Based on the storage network constructed by Hadoop, cloud storage systemguaranteed the high usability through the employment of Hadoop’s internal datamanagement system. This study analyzes and summarizes the characteristics ofrelevant data of wisdom and constructs extensible data model in HBase in which allthe data resources of cloud storage system are stored in according to the inner datamodel. Cloud storage system includes the proscenium online storage system withlarge capacity and backstage management system in which users can upload,download, manage and do etc. operations to the relevant data of wisdom educationthrough the proscenium online storage system and system administrator can have asystem management of software and hardware resource in the cloud storage systemthrough the backstage management system.The cloud storage system for wisdom education reduces the construction costswhose superior data storage service not only satisfies the storage needs of vast dataresources of current wisdom education, but also supports the increasing backstagestorage needs of the wisdom education cloud platform and guarantees the effectiveoperation of wisdom education cloud platform.更多还原
