1、基于云计算的数据库关键技术研究 摘 要云计算作为近年来研究与应用领域的热点话题,被大多数IT企业和业内人士认为是下一代计算机网络应用技术的核心架构。云计算环境下,使用者可以不用再花费高昂的硬件和软件成本去拥有强大的计算资源和庞大的存储能力,所有这一切都可以交给云计算服务提供商来完成。目前,设备的信息化管理系统的研发得到了企业的高度重视。由于国内企业的设备现代化程度低、自动化水平落后、设备参差不齐,没有完善和明确的设备故障远程诊断和管理等问题,国内开发的设备管理软件的功能仍然停留在对设备的基本信息等静态数据的管理上,不能满足用户以及应用增长的需求。而云计算平台技术的应用,不仅消除了用户对特定设备
2、的依赖,而且规模可以根据用户和应用增长的需求进行伸缩。凭借云,用户的应用和文档仍然跟随用户,用便携的设备,同样使用自己的应用和文档记性大量的计算和远程管理。本文主要借鉴云计算体系结构,对NoSQL关键点进行研究。论文在对NoSQL 相关技术进行阐述的基础上,研发并实现了一个基于云计算平台的企业设备管理系统。该系统能够为企业建立完整的仪器设备电子档案,对仪器设备的信息进行数字化管理,提高企业设备管理水平。该系统主要包括设备管理模块、统计分析模块、系统管理模块等九大模块。该系统最大的特点是可以不受到某些外界条件的限制(如地域和时间),是未来设备管理系统的一个发展方向。关键词: 云计算;数据库;No
