The need for efficient and scalable data management has increased in the contemporary distributed mobile and fixed networks. Sharing growing amounts of multimedia data stored in autonomous, heterogeneous and distributed equipment such as mobile devices, personal computers, enterprise servers etc. is a trend, especially considering peer-to-peer networking scenarios. In this paper we describe a simple yet extendable analytical model to enable comparison of various aspects of the existing and emerging distributed data management systems. We introduce an abstract model for analyzing service enabler efficiency indicating operational costs for system external and internal parameters. Model is applied to benchmark distributed data management techniques to support optimal design choices, especially considering the design guidelines for data management in mobile P2P environments.
