Oracle In-Memory Database Cache enables you to improve application transaction response times and throughput by caching performance-critical subsets of an Oracle Database in the application tier. Automatic data synchronization between the cache and the Oracle Database ensures data consistency. By bringing data closer to the application and processing queries in an in-memory database, your applications are able to access, capture, or update information many times faster. The Oracle In-Memory Database Cache (IMDB Cache) option of Oracle Database 11g caches and processes data in the memory of the applications themselves; off-loading the data processing to middle tier resources. Any network latency.
