The BaBar experiment at the Stanford Linear Accelerator Center is designed
to study CP violation in decays of B mesons produced in electron-positron
interactions. BaBar has chosen an Object Oriented Database Management System,
Objectivity/DB, as the underlying storage technology. The online system
has also adopted Objectivity to store ambient data from the Detector
Controls, the Fast Monitoring histograms and the configuring parameters of
various hardware and software components of the detector. Over 100 GB
of non-physics data will be recorded each year.
The online databases will be presented with emphasis on the design and
implementation of the Ambient and Configuration databases. Their performance
during the first run of the experiment will be discussed. Online database
servers and browsers will also be described.
