When you are automating a number of tasks, or performing a batch of tests, you want a way of automating the production of your plots and graphs. Nothing beats a good graphical plot for giving the indications of how the process went. If you are using PowerShell and maybe also SQL Server, it pays to use a command-line plotting tool such as Gnuplot to do all the hard work. It turns out to be handy for a range of data jobs, turning PowerShell into a handy data science tool.

If you’re a Redgate SQL Backup customer, occasionally you’ll need to convert your SQL Backup (.sqb) files to the native SQL Server backup format (.bak), perhaps to perform native database restores on a server where SQL Backup isn’t installed. This produces a striped backup, because each thread used when making the backup will produce a separate file. Can we use a striped backup produced in this way, or indeed any striped backup, as the source for a SQL Clone image? Short answer: we can! Let’s see how that works.

The network is important to any DBA because so much performance is dependent on I/O, because of the importance of security, and ensuring that everyone get the right access. DBAs generally need not become experts in Azure networks, but it helps to understand the concepts and language.
