摘要

In most web digital libraries, picture databases play an important role in making the contents more completed, illustrative and attractive. However, in some special purpose (e.g. for education or for news publication) digital libraries, in which picture databases are absolutely necessary at the back end, the phenomenon of "hotspot" often pulls down the response speed of queries on picture databases and makes the whole performance decline seriously. This paper brings forward the idea of caching "hot" data in a pool to alleviate the above problem. And by utilizing the characteristics of "hotspot", we implement a light-weighted cache pool which is very effective in improving picture access performance.
