Dynamic caching
In general, caching improves response time and reduces system load. Caching techniques are used to improve the performance of World Wide Web Internet applications. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many websites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the WebSphere Application Server dynamic cache, a built-in service for caching and serving dynamic content.
WebSphere Commerce data cache
Enterprise and Professional versions of WebSphere Commerce contain code to use the WebSphere Dynamic Cache facility to perform more caching of database query results. This additional caching code is referred to as the WebSphere Commerce data cache.

With a few exceptions, such as the FlexFlowCache, the data cache is disabled by default. You must enable the data cache before it can begin to cache data.
