Abstract: “Data caching mechanism for query processing in database turned the researchers due to its performance such as minimum access of latency time, reduced network traffic ,pre fetched data etc, As extension with semantic data caching further made interest among not only the database researchers but also the design and developers even at application level ,due to the existence of data along with its description, pre-processed result which drastically improved the processing speed and user convenience, irrespective of the area such as semantic cache based query processing over peer to peer network, web environment, parallel distributed database,artigficial intelligence,fuzzysets ,mining and cloud. In this paper with this significance a survey is made based on efficiency of query processing as well as pros and cons of existing caching techniques and presented as amending assistance for the database people for enhancement of real world application.”

Keywords: semantic caching, query processing
