Adding the decision logic

Automation Decision Services provides two ways to define the decision logic of node: business rules and decision tables.

Business rules are conditional statements. Basic business rules use an if-then statement to state what action to perform when specific conditions are met. In the following example, the rule outputs a message encouraging people to stay home if there is a storm alert:

if
     Weather is storm alert 
then
    set decision to "It would be wise to stay home. There is a storm alert." ;

More complex business rules can consist of up to four parts: definitions, if, then, and else.

Decision tables allow you to model complex logic. Their tabular layout helps you effectively document all the possible conditions and results of a decision node. In the following example, the decision table consists of two inputs, the condition columns Rain forecast and Temperature, and an output column, Weather advice. It gives a recommendation on what to bring depending on the weather: a coat, some water, or an umbrella.

You can use input data and the output of subdecisions while defining the logic of a decision node.
