Virgo is an experiment carried out by INFN (Italy) and CNRS (France) to detect gravitational waves using a long baseline (3 X 3 km) interferometer, that requires a strong integration process among the various subsystems, for the functional coupling of the real-time control, database, communication, and visualization aspects of the project. In this paper we present the system architecture and illustrate some of the subsystems with particular emphasis on the data retrieval and processing, used in the monitoring and data storage subsystems.
