Data grid system based on agent for interoperability of distributed data

This paper presents data grid system based on agent for an efficient interoperability of distributed data. Purpose of the data grid system is an efficient interoperability through sharing and exchanging data among distributed databases. Interoperability of distributed data is a basic condition for cooperation of existing legacy systems. More nodes for cooperation, better for distributed environment. On the other hand, we have to overcome heterogeneous characteristics of data and physical problems of network. Therefore, we use agent system which is independent, autonomous and mobile in distributed platform for solving this problem. As mobile Agent interacts asynchronously, it could lessen network traffic and support workload and distributed processing of services so that it is suitable for data grid system. Also we use XMDR(eXtended Metadata Registry) in ISO/IEC 11179 for sharing and exchanging data and overcome the heterogeneity of data. Therefore we improve availability and transparency of distributed data based on data grid middleware using proposed mobile agent and could construct data grid system with low cost.
