An Introduction to SDSS and its Database

Jurek Krzesinski

The Sloan Digital Sky Survey is the largest and most successful sky survey of the Northern and part of the Southern celestial hemispheres ever made. The survey was performed using a dedicated 2.5 m telescope, the state-of-the-art imaging camera and spectrographs. It resulted in five band photometry of more than 14 000 square degrees of the sky, as well as over 4 000 000 unique spectra of galaxies, quasars and stars. The data are publicly available in the form of images, optical spectra, infrared spectra, and catalog data. All data can be downloaded from several di erent online sources. In this review I will present the past and current status of the Sloan Digital Sky Survey and wills introduce two main database web sites: ScienceArchiveServer and SkyServer.
