| Abstract: |
Astronomical catalogues containing from a million up to hundreds of millions of records are becoming commonplace. While they are of fundamental importance to support operations of current and future large telescopes and space missions, they appear also as powerful research tools for galactic and extragalactic astronomy. Since even larger catalogues will be released in a few years, researchers are faced with the problem of accessing these databases in a general but efficient manner, in order to be able to fully exploit their scientific content. Traditional database technologies (i.e.\ relational DBMSs) have proved to be inadequate for this task. Other approaches, based on new access technologies, must thus be explored. In this paper we describe the results of our pilot project aimed at assessing the feasibility of employing Object--Relational DBMSs for the management of large astronomical catalogues. |
