Abstract

ANTARES is a telescope for neutrino astronomy installed in the Mediterranean Sea at a depth of about 2500 m. While the event data are stored in root files, an Oracle 10 G Relational Data Base Management Server (RDBMS) is used for storing structural, control and monitoring information. The database includes complete configuration tables for the whole detector, allowing to store calibration information for each acquisition chain element. Such an information is stored in a large number of tables with relational behavior, in order to maintain the necessary correlations between the different data entries. This complex structure has been designed, so as to facilitate the development of the software for acquisition and analysis of the ANTARES data. In this paper the structure of the ANTARES database is illustrated for what concerns two major functionalities: calibration and apparatus configuration.
