Abstract: Aiming at the problems of traditional remote images pyramid unitary store model in multi-user parallel access application, this paper proposes a separable store model suitable for multi-user parallel access, which makes use of distributed data store and processing task decomposition and transferring to improve I/O performance and response efficiency of data servers. Experimental result proves that the effectiveness of the model, and the model system has good expansibility and stability.

Key words: separable store model, clustered store, parallel access, distributed store, task decomposition
