With the introduction of Oracle Database In-Memory, a single database can now efficiently support
mixed workloads, delivering optimal performance for transactions while simultaneously supporting
real-time analytics and reporting. This is possible due to a unique "dual-format" architecture that enables data to be maintained in both the existing Oracle row format, for OLTP operations, and a new purely in-memory column format, optimized for analytical processing. In-Memory also enables both datamarts and data warehouses to provide more ad-hoc analytics, giving end-users the ability to ask multiple business driving queries in the same time it takes to run just one now.
