Model of semantic cache in heterogeneous data integration system
Wei Li, Zhang Jun · Journal of Dalian Maritime University · 2004
We introduce a caching scheme which is called semantic caching. Unlike the traditional page caching, tuple cache etc., the semantic cache is defined and accessed based on the queries submitted by the client. Both the predicate and the resulting tuples of queries are cached. When a new query is requested, the partial or whole result may be obtained through query processing on the semantic cache. Only the rest query is submitted to server. Data Caching at local clients plays an important role in improving the performance of client-server systems. In this article, with investigating current researches about semantic cache and taking account of the character of our research, we propose a kind of model of semantic cache.
