云计算与高校数字图书馆建设研究

Investigation of University Digital Library Construction Based on Cloud Computing

数字图书馆具有开放性、虚拟性、资源分布性、数据异构性、访问异步性等特点,构成了国家开放大学远程教育的教学活动中重要的知识支撑平台。云环境是互联网、大数据技术、分布式计算技术发展的产物,恰能满足高校数字图书馆建设中对物理资源、数据资源的使用需求。构建基于云环境的数字图书馆需要在管理体制、服务方式、运营方式上进行创新,在技术上需要遵循构建PaaS、SaaS、IaaS三层数字图书馆体系结构,实现云环境与数字图书馆建设的融合。

Digital library is an open and virtual system with distributed resources, heterogeneous data and asynchronous access as its characteristics, which is a knowledge platform for distance education of the Open University of China. The cloud environment, which can meet the needs for physical resources and data resources in digital library construction, emerges as the result of the intemet technology, the big data technology and the distributed computing technology. Building a digital library based on cloud environment needs to innovate in management system, service mode and operation mode. It is technically necessary to follow the construction of three-layer digital library architecture of PaaS, SaaS and IaaS to realize the fusion of cloud environment and digital library construction.
