  The configuration database is one of the vital systems in the BaBar on-line
system. It provides services for the different parts of the data acquisition
system and control system, which require run-time parameters. The original
design and implementation of the configuration database played a significant
role in the successful BaBar operations since the beginning of experiment.
Recent additions to the design of the configuration database provide better
means for the management of data and add new tools to simplify main
configuration tasks. We describe the design of the configuration database, its
implementation with the Objectivity/DB object-oriented database, and our
experience collected during the years of operation.
