Most of the data and modeling tools in IBM SPSS Modeler reside in the Nodes Palette, across the bottom
of the window below the stream canvas.
For example, the Record Ops palette tab contains nodes that you can use to perform operations on the
data records, such as selecting, merging, and appending.
To add nodes to the canvas, double-click icons from the Nodes Palette or drag and drop them onto the
canvas. You then connect them to create a stream, representing the flow of data.
