Creating a simple transformation

Transformations and jobs are the main PDI artifacts. Transformations are data-flow oriented entities, while jobs are task-oriented. In this book, we will start by learning all about transformations, focusing on jobs later. To get a quick idea of what, exactly, a transformation is, we will start by creating a simple one. This will also allow you to see what it's like to work with Spoon.

Our first transformation will find out the current version of PDI (Kettle), and will print the value to the log. Proceed as follows:

• On the Welcome page, click on the New transformation link, located under the WORK link group. Alternatively, press Ctrl + N.
• A new tab will appear, with the title Transformation 1. It's in this tab that you will create your work.
• To the left of the screen, under the Design tab, you'll see a tree of folders. Expand the Input folder by double-clicking on it.

Note

Note that if you work in macOS, a single click is enough.

• Then, left-click on the Get System...
