What has Oracle done to R to give us ORE
Oracle R Enterprise (ORE) was officially launched over the past couple of days and it has been receiving a lot of interest in the press.
We now have the Oracle Advanced Analytics (OAA) option which comprises, the already existing, Oracle Data Mining and now Oracle R Enterprise. In addition to the Oracle Advanced Analytics option we also 2 free set of tools available to use to use. The first of these free tools are the statistical functions which are available in all versions of the Oracle Database and the second free tool is the Oracle Data Miner tool that is part of the newly released SQL Developer 3.1 (7th Feb).
What has Oracle done to Oracle to make Oracle R Enterprise ?
The one of the main challenges with using R is that it is memory constrained, resulting in the amount of data that it can process. So the ORE development team have worked ensuring R can work transparently with data within the database. This removes the need extract the data from the database before it can be used by R. We still get all the advanced on in-Database Data Mining.
They have also embedded R functions within the database, so we an run R code on data within the database. By having these functions with the database, this allows R to use the database parallelism and so we get quicker execution of our code. Most R implementation are constrained to being able to process dataset containing 100Ks of records. With ORE we can now process 10M+ records
In addition to the ORE functions and algorithms that are embedded in the database we can also use the R code to call the suite of data mining algorithms that already exist as part of Oracle Data Miner.
