Abstract :
The Sloan Digital Sky Survey (SDSS) project has gathered or produced about 40 terabytes of data since it started in 2000. The data is made available on the Internet through the SkyServer Web interface, for use by professional astronomical researchers and the general public. We first consider how the database´s design helps explore the Sloan data. Then we describe our experience mirroring the SDSS database. We also discuss our preliminary work with distributing the multi-terabyte database across different UK sites using the OGSA-DAI middleware
