They give you many ways of manipulating and analyzing data and passing it between R and SQL Server.

Some time ago, Phil Factor wrote his booklet 'SQL Code Smells', collecting together a whole range of SQL Coding practices that could be considered to indicate the need for a review of the code. It was published as 119 code smells, even though there were 120 of them at the time. Phil Factor has continued to collect them and the current state of the art is reflected in this article. There are now around 150 of these smells and SQL Code Guard is committed to cover as many as possible of them.

It is certainly true that some of the more extravagant delays can be fairly blamed on a missing index or unnecessary locking, but there are other potential villains in the drama, including the network and the application itself.

The working life of the DBA can be punctuated by surprises, but they aren't generally nice surprises.

However, the really scary surprises are less obvious and provide fewer warning signs. Brent Ozar gives six scary surprises that can be avoided by the shrewd DBA.

I have a need to decrease the time my SQL Server database backups are taking to run. I thought about trying to run multiple backups at the same time to see if that would work. I could have created multiple SQL Server Agent Jobs to run at the same time, but I wanted a more dynamic way to handle this, so I created a PowerShell script that allows processes to run in parallel.
