RevoScaleR is a library of high-performance data science
functions from Microsoft. Functions support data import, data
transformation, summarization, visualization, and analysis.
In contrast with base R functions, RevoScaleR operations can
be performed against very large datasets, in parallel, and on
distributed file systems. Functions can operate over datasets
that do not fit in memory by using chunking and by
reassembling results when operations are complete.

9. Why ML in SQL?
Bring Data to Processor
ML needs data and processor, which SQL Server has both assets.
Predict in transaction
Prediction runs in transaction of SQL.
Publish Model
SQL stores model as binary and easy to maintain versions.
