Grid applications deal with large volumes of data. As a consequence, effective data management solutions are vital for grids. The Clusterix Data Management System (CDMS) has been developed after a careful analysis of end-user requirements and existing implementations. A special attention has been paid to making the system user-friendly and efficient, aiming at the creation of a reliable and secure Data Storage System. For example, taking into account network parameters, CDMS tries to optimize data throughput via replication and replica selection techniques. Another key feature considered during the development is fault tolerance. In CDMS the distributed operation model and modular design assure elimination of single point of failure. In particular, multiple instances of the data broker are running concurrently, and their coherence is ascertained by the synchronization subsystem. This paper presents the concept and details of implementation of data management mechanisms adopted in CDMS, as well as its integration with applications.
