What you have described is half of the usage of binding variables. You can bind a variable to a fact or to individual fields of a fact. You can then use those variables in the LHS or the RHS of your rules.

For example:

1.- Find different Person objects

when

$p1: Person($name1: name)

$p2: Person($name2: name, this != $p1)

then

System.out.println("Found "+$p1+" with name '"+$name1+"' and "+$p2+" with name '"+$name2+"'");

end

Hi,

I am having little bit difficulty in understanding "binding variable"
concept in the guvnor. During our POC a business user asked me question
around this and i was able to save myself by telling them that the binding
variable is used in case you want use the fact again in Then statement.
(This is how i see it in the examples of rules).

Can anyone please explaining me the real use of the binding variable so that
i can help my business partner understand it properly?

Thank you for your help in advance
