Development of Information Systems for Online and Offline Data Processing in the NICA Experiments

Acquiring, storing, processing and analyzing experimental and simulated data are an integral part of all modern high-energy physics experiments. These tasks are of particular importance in the experiments of the NICA megaproject at the Joint Institute for Nuclear Research (JINR) due to the high interaction rate and particle multiplicity of ion collision events. Therefore the task of automating the considered processes for the NICA complex is a very urgent topic. This article describes the status of the development of new information systems as well as a set of convenient information services for collaboration members to automate storing and processing of data and information on the experiments. The Geometry Information System and Online Electronic Logbook, which are on the final stage of implementation, are presented. In addition, the design of the Condition Database and Event Metadata System, which are scheduled to be completed next year, are described in detail. The systems provide storing of information required for event processing and physics analysis and organize a transparent, unified access and data management throughout the life cycle of the scientific research in the NICA megaproject. One of the key aspects—the integration of the information systems with the experiment software systems—is also presented.
