Development of the Sloan Digital Sky Survey online systems

The Sloan Digital Sky Survey (SDSS) is an astrophysics project to produce a three dimensional map of a quarter of the Universe. We present a description of the SDSS prototype, the Drift Scan Camera (DSC) online system, which is operational and currently being deployed. We also present the status of the development of the SDSS online system. The hardware and software architectures for both systems are provided.<
