Define Input

It’s hard to make a good decision without input (or data). For our “What to Bring for the Weather” example, the input will be two numbers: temperature and rain percent forecasts. Let’s set up their definitions.

1. Click Show data panel to expand the Input Data pane.
2. Add a complex type definition for the forecasts.
   1. In the Type Definition section, click Add new item definition .
   2. In the Name field, enter ForecastType.
   3. In the Mode field, select Complex.
   4. Click Add Component next to Define Type Attributes to add two attributes.
   5. For the first attribute, enter Temperature for its name and select Number as its mode. Click Close to return to the Add Type Definition panel.
   6. For the second attribute, enter Precipitation for its name and Number as its mode.
   7. Click Close.

   3. In the Mode field, select Other Type.
