Oracle Database, Oracle Corporation’s flagship product, is a commercial object-relational database management system. It provides large organizations an enormous feature set out-of-the-box. Those core features include logical data storage using tablespaces; table partitioning based on key sets; and database monitoring and tracking. Oracle Database offers extensions to customize the system’s core functionality. Known as "database options," they include such features as Advanced Compression; Advanced Security using data encryption; Content Database to store unstructured data; Data Mining to find patterns among existing data; and an In-Memory Database Cache that leverages TimesTen technology. Oracle also provides its customers the option to install additional "Management Packs," designed to leverage cutting-edge database technologies like multitenancy, cloud file systems, and OLAP (Online Analytical Processing), among other things.
