【摘要】：随着新一代巡天观测、时域观测等天文项目的推进,当前的天文数据量越来越大。面对天文领域日益增长的大数据集和大数据流,需要一些高效的数据存储和数据处理方法来对数据进行管理。天文数据库以及在其基础上提供的数据服务的出现部分解决了这样的问题。借助于计算机技术和信息技术的进步,一些更加专业的针对天文领域的数据发现、数据挖掘、数据交互等工作正在逐步标准化。基于虚拟天文台技术和天文信息学的新型天文数据服务正深入天文用户的日常科研生活中。首先简单回顾了天文数据库的历史,然后通过对几个典型天文数据库的举例分析,从天文数据库的类型、提供的服务等方面介绍了当前天文数据库的特点和最新进展,并对今后天文数据库的发展做了展望。
[Abstract]:With the advance of the new generation of astronomical projects, such as the survey of the sky and the time domain observation, the current astronomical data is becoming larger and larger. In the face of the growing big data collection and large data flow in the astronomical field, some efficient data storage and data processing methods are needed to manage the data. The emergence of astronomical databases and the data services provided on their basis partially solves this problem. With the development of computer technology and information technology, some more professional data discovery, data mining and data interaction are being standardized step by step. New astronomical data services based on virtual observatory technology and astronomical informatics are being applied to astronomical users' daily scientific research. In this paper, the history of astronomical database is briefly reviewed, and then through the analysis of several typical astronomical databases, the characteristics and latest progress of the current astronomical databases are introduced from the aspects of the types and services of astronomical databases. The future development of astronomical database is prospected.
