Abstract

The core API of Hibernate provides several query interfaces,which complete query function with the using of HQL、QBC and SQL language. This paper shows the realization method of these interfaces and application process of query language. In order to improve query performance,the paper analyzes the caching mechanism and retrieval strategy to determine the reasonable query mode which can optimize SQL sentence,reduce frequency of database accessing and save internal memory resource.
