一种适合多用户并发访问的影像存储模型

Image Store Model Suitable for Multi-user Parallel Access

针对传统的遥感影像金字塔一体化存储模型在多用户并发访问应用中的存在的问题,提出一种适合多用户并发访问的可分离式存储模型,通过数据的分布存储和访问处理任务的分解、转移,提高数据服务器的I/O性能和响应效率。实验结果证明了该模型的有效性,且模型系统具有较高的可扩展性和稳定性。

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.
