Development Methodology of the Data Management System for the BM@N Experiment

Methodology for developing the data management system (DMS) for BM@N, a fixed target experiment at the NICA (Nuclotron-based Ion Collider fAcility) project is presented. The data management system provides all the necessary tools for secure and efficient data transfer, file cataloging and replication of the experiment data. The goals of implementation of the DMS logging and monitoring services, integrity and consistency checks, user interfaces and authorization are described. One of the key points in the development methodology is focused on providing universal access to file replicas, as well as implementation of a file (or dataset) metadata service for the efficient search of data required for a specific processing or physics analysis.
