SQL Server 2017 Machine Learning Services with R.

By: Julie Koesmarno, Tomaž Kaštrun

Overview of this book

R Services was one of the most anticipated features in SQL Server 2016, improved significantly and rebranded as SQL Server 2017 Machine Learning Services. Prior to SQL Server 2016, many developers and data scientists were already using R to connect to SQL Server in siloed environments that left a lot to be desired, in order to do additional data analysis, superseding SSAS Data Mining or additional CLR programming functions. With R integrated within SQL Server 2017, these developers and data scientists can now benefit from its integrated, effective, efficient, and more streamlined analytics environment. This book gives you foundational knowledge and insights to help you understand SQL Server 2017 Machine Learning Services with R. First and foremost, the book provides practical examples on how to implement, use, and understand SQL Server and R integration in corporate environments, and also provides explanations and underlying motivations. It covers installing Machine Learning Services;maintaining, deploying, and managing code;and monitoring your services. Delving more deeply into predictive modeling and the RevoScaleR package, this book also provides insights into operationalizing code and exploring and visualizing data. To complete the journey, this book covers the new features in SQL Server 2017 and how they are compatible with R, amplifying their combined power.

Integrating R workloads and prediction operations beyond SQL Server

In this section, you will learn how to include R workloads and prediction operations that you have created in the previous sections beyond SQL Server. We will discuss how to run the workloads and operations in PowerShell, SQL Agent Job, and SQL Server Integration Services (SSIS).

Please note that you can also execute these workloads/prediction operations using SQLCMD, C# within SSIS, Azure, and also Bash on Linux. This discussion is beyond the scope of this chapter.

Executing SQL Server prediction operations via PowerShell

Assuming that you have already created the stored procedure that executes R script from SQL Server, such as [dbo].[uspTrainTipPredictionModel...
