For demonstration purposes, this book refers to the Samples-Data sample (https://github.com/intersystems/Samples-Data). You might find it helpful to download and set up this sample, but doing so is not necessary. If you do download the sample, InterSystems recommends that you create a dedicated namespace called SAMPLES (for example) and load samples into that namespace. For the general process, see Downloading Samples for Use with InterSystems IRIS.
