基于HDFS的分布式教学资源平台设计与实现

Based on the distributed HDFS platform design and implementation of teaching resources

教学资源管理是提高教学质量和促进教育资源均衡的重要因素,分布式存储是解决目前教学资源数据量大、存储成本高和访问速度慢的有效手段。基于HDFS技术展开研究,为系统开发提供技术支持。研究内容以HDFS体系结构为基础,遵循"松散耦合"的思想,设计了由基础设施层、支撑平台层、软件功能层和用户接入层构成的四层平台架构;使用HDFS技术,实现了读取文件和写入文件等核心功能。研究成果解决了软件开发关键性技术问题,开发过程中要充分发挥HDFS的优点,以提高软件的质量和性能。

Teaching resources management is an important factor to improve the quality of teaching and to promote the balance of educational resources, and distributed storage is an effective mean to solve the problem of large plenty of teaching resources, high storage cost and slow access. Based on HDFS technology to provide technical support for system development. Based on the HDFS architecture, the four-layer platform architecture composed of the infrastructure layer, the support platform layer, the software function layer and the user access layer is designed according to the idea of ＂loose coupling＂ ;by using HDFS technology, reading the file, writing the file and other core functions come true. The research content of solves the key technical problems in software development, the development process should give full play to the advantages of HDFS to improve the quality and performance of the software.
