1 Overview for the Oracle TimesTen In-Memory Database

Oracle TimesTen In-Memory Database (TimesTen) is a memory-optimized relational database that empowers applications with the responsiveness and high throughput required by today's real-time enterprises and industries such as telecom, capital markets, and defense. TimesTen supports SQL, standard APIs, complete ACID properties, and highly available replication mechanisms. The database resides entirely in physical memory and is persistent and recoverable.

• Oracle TimesTen In-Memory Database is a memory-optimized relational database that provides applications with the responsiveness and high throughput. High availability for the in-memory database is provided through transactional replication.

• Cache is ideal for caching performance-critical subsets of an Oracle database for improved response time in the application tier. Cache tables can be read-only or updatable. Applications read and update the cache tables using standard SQL, and data synchronization between the cache and the Oracle database is performed automatically. Cache offers applications the full generality and functionality of a relational database, the transparent maintenance of cache consistency with the Oracle database, and the high performance of an in-memory database.
