Semantic caching techniques in data processing mediator systems
Zhiqiang Zhao · Harbin Gongcheng Daxue Xuebao/Journal of Harbin Engineering University · 2007
A high performance data processing mediator system mediates parallel data processing using semantic caching technology.In this paper,an improved semantic caching method is proposed that improves the efficiency of the system by also correlating the user's queries to reduce network communication costs.The framework and primary modules of the mediator are described in detail.Then,the basic idea of semantic caching strategy,cache configuration,replacement strategies,and maintenance methods are discussed.Experimental results indicate that this technology can greatly improve system performance and response capability.This mediator system has already been put into use in a large national engineering project.
