A graph object oriented database model in distributed environment

The graph data model allows us to view a database in a graph G(V,E). For any large semi-structured application under distributed environment, the entire database needs to be fragmented at different sites for better utilization of the existing resource. The graph model also needs the fragmentation in such a way that the fragmented subgraphs can constitute the original graph without any loss. In this paper, the proposed graph data model has been utilized in a distributed environment with suitable examples in the area of a hospital management system.
