The BaBar experiment at the Stanford Linear Accelerator Center studies the CP violation
in the decays of neutral B mesons produced in electron-positron collisions in the PEP-II asymmetric
B-factory. The experiment began its operation in May of 1999, and will take data over the period of
10 years.
A special database is being used by the experiment to keep the detector alignments,
calibrations constants, as well as other time-dependent records of the conditions under which the
events are being taken.
The layered complex of the software, providing the mechanism for storing, retrieving and managing
these data is referred to as the conditions database.
The BaBar conditions database software makes use of a commercial Object Oriented
database with C++ interface as an underlying storage technology.
This talk will present the wide spectrum of aspects associated with the current design
and the implementation of the conditions database software, ranging from its architecture, the
internal structure of the database, performance studies, to the experience gained during the first
months of the detector's operation.
