在大数据天文学时代，下一代望远镜和大型巡天仪可以产生TB甚至PB级别的数据集。由于其庞大的数据量，这些天文数据集非常难以使用个人计算机或小型集群进行传输和分析。为了提供更好的数据访问，数据中心现在通常提供在线科学平台，使分析接近数据。中国虚拟天文台（China-VO）是国际虚拟天文台联盟的成员项目之一，致力于提供一个研究和教育环境，使全球分布的天文学档案易于查找，访问和互操作。在这项研究中，我们总结了在中国VO进行的工作的亮点，以及在天文数据的全生命周期管理过程中吸取的经验和教训。最后，我们讨论了天文科学平台面临的挑战和未来的发展趋势。(C)2020爱思唯尔B. V.保留所有权利。
In the era of big data astronomy, next generation telescopes and large sky surveys produce data sets at the TB or even PB level. Due to their large data volumes, these astronomical data sets are extremely difficult to transfer and analyze using personal computers or small clusters. In order to offer better access to data, data centers now generally provide online science platforms that enable analysis close to the data. The Chinese Virtual Observatory (China-VO) is one of the member projects in the International Virtual Observatory Alliance and it is dedicated to providing a research and education environment where globally distributed astronomy archives are simple to find, access, and interoperate. In this study, we summarize highlights of the work conducted at the China-VO, as well the experiences and lessons learned during the full life-cycle management of astronomical data. Finally, We discuss the challenges and future trends for astronomical science platforms. (C) 2020 Elsevier B.V. All rights reserved.
