A Coherence cache is a collection of data objects that serves as an intermediary between the database and client applications. Database data can be loaded into a cache and made available to different applications. A Coherence cache reduces load on the database and provides faster access to database data. Objects in the cache can be either XML or Plain Old Java Objects (POJOs). The Coherence adapter enables you to perform the following operations against a Coherence cache.

• Add an item

• Obtain an item

• Remove an item

• Query for an item
