摘　　要：天文数据主要包括星表、星图、光谱、文献资料等,其中星表是包含天体信息的数据表格,是天文学家最常用到的天文数据。目前天文数据分布存储在全球各个数据中心。中国最大的天文数据中心是北京天文数据中心,其数据库的重要部分是天文星表数据库。本文阐述了建设天文星表数据库的意义,着重探讨了星表自动入库工具的实现,并介绍了在天文星表数据库基础上的数据融合和数据挖掘。Astronomical data mainly includes catalogues, images, spectra and literatures, etc. The catalogues are the data tables containing astronomical information and are often used. At present, astronomical data are distributed and saved in the global various data centers. The largest astronomical data center in China is the Beijing Astronomical Data Center. The important part of the astronomical databases is the database of astronomical catalogues. In this paper, the significance of constructing the catalogue databases is reviewed, the realization of the automated tool to put catalogues into databases is mainly probed, and data integration and data mining based on the database are also described.
