Paper Abstract

Astronomy steps into a fullwave and data-avalanche era. Astronomical data is measured by Terabyte, even Petabyte. How to save, manage, analyze so massive data is an important issue in astronomy. In order to let astronomers free of the data processing burden and expert in science, various valuable and convenient tools (e.g. Aladin, VOSpec, VOPlot) are developed by VO projects. To suit this requirement, we develop a toolkit to realize automated database creation, automated database index creation and cross-match. The toolkit provides a good interface for users to apply. The cross-match task may be implemented between local databases, remote databases or local database and remote database. The large-scale cross-match is also easily achieved. Moreover, the speed for large-scale cross-match is rather satisfactory.
