Larry Ellison announced in “Oracle Open World 2013” that in 12c database version and optional feature for “in-memory” is added for big data analytic. This will accelerate performance dramatically.

According to Ellison there is no need to do any data migration or application (in-house or off the shelf) changes.

Oracle is trying to compete with the successfully commercial in-memory database SAP HANA. SAP were successful in their implementation, and many customers have used the technology. The in-memory database is the future for big data implementation in the enterprises. Other companies like IBM and Microsoft are also catching up and are in the process of developing their own “in-memory” products solutions.
