jBRMS Rules definition for Business Users (non-technical folks)

Folks, any pointsers on my below request please?

Hello Experts,

We are new to this technology and would like to explore options to define rules for business users who are non-technical folks. Other than decision tables, does jBRMS provide any kind of friendly user interface to define simple as well as complex rules and then extract a .drl file out of that for further processing? Can someone shed light on this?

Thanks!
