N1 - Funding Information:
That is about to change. Now under construction in the United States and Europe are large detectors whose design sensitivity is so great that they will be capable of measuring the minute influence of gravitational waves from strong, but distant, sources. The United States project, the Laser Interferometer Gravitational-wave Observatory (LIGO), is funded by the National Science Foundation under contract to the California Institute of Technology and the Massachusetts Institute of Technology.

It is a pleasure to acknowledge Kent Blackburn, Albert Lazzarini, and Roy Williams for many helpful and informative discussions on the technical details of the LIGO data analysis and archive system design. The ideas discussed here on the use of the on-line and off-line data analysis system have been informed by discussions with Rainer Weiss. This work was supported by National Science Foundation award PHY 98-00111 to The Pennsylvania State University.

N2 - LIGO - The Laser Interferometer Gravitational-Wave Observatory - is one of several large projects being undertaken in the United States, Europe and Japan to detect gravitational radiation. The novelty and precision of these instruments is such that large volumes of data will be generated in an attempt to find a small number of weak signals, which can be identified only as subtle changes in the instrument output over time. In this paper, I discuss how the nature of the LIGO experiment determines the size of the data archive that will be produced, how the nature of the analyses that must be used to search the LIGO data for signals determines the anticipated access patterns on the archive, and how the LIGO data analysis system is designed to cope with the problems of LIGO data analysis.
