Hello Geeks

Probably this would be quite a trivial question but i wanted to know why at all there is a need of Cache System ? What is the difference between all these cache systems availaible ?

Any video about general talk about cache would be great .
Any tutorials about Ehcache to learn ?
Any book for the same ?

Thanks and Warm Regards

Caching is done for performance reasons; start reading here: Cache (computing). For EhCache in particular, its web site has lots of introductory material, including a "Getting Started" document.

These days people are more likely to ask "why not to use caching"?. With the vast increase in memory space and cpu speeds gone are the days when the caching was hevy on system and it is must for a scalable solution. Having said that a proper list should be maintained of the properties being cached and when to update/refresh them and it is always good to have it well documented. I like the EHCache. A good link to Video
