Decision Table Use Case: Graphic Rendering
The application scenario:
- Graphical user interface for a railway signalman with more than 20
element categories (signals, switches, etc.)
- Graphic rendering based on 5 to 25 boolean status properties per category
- Specification by a collection of examples with arbitrary

- Conventional approach "too difficult"
- The consequence: use decision tables!
A selection of states for a switch, an element with 20 status values:
