Not having direct access to database-resident data introduces delays in obtaining data, and can make near real-time analytics impossible. In some instances, users request data sets much larger than required to avoid multiple requests to IT. Of course, this approach introduces costs of exporting, moving, and storing data, along with the associated backup, recovery, and security risks.
Oracle R Enterprise eliminates the need to know SQL to work with database-resident data. Through the Oracle R Enterprise transparency layer, R users can access data stored in tables and views as virtual data frames. Base R functions performed on these "ore.frames" are overloaded to generate SQL which is transparently sent to Oracle Database for execution - leveraging the database as a high-performance computational engine.
