Data management and processing system for the Baikal-GVD telescope

The Baikal-GVD neutrino telescope is being constructed in lake Baikal. The robust Baikal Analysis and Reconstruction Software (BARS) has been developed to convert raw data into physics results. To provide a stable and continuous analysis of all the data an automatic data processing using database is developed. The flexibility of the concept makes it easy to add new steps at any point of the analysis chain. The software is ROOT based collection of C++ classes driven by a central event loop. Now the basic algorithms have been implemented in the system such as event building, signal extraction, background rejection and simple reconstruction.
