Rule engines are a powerful yet flexible tool to define and implement huge sets of business requirements and constraints. While Drools Rule Language (DRL) may be appealing to define business rules for technically savvy domain experts, a new visual based standard has emerged in the Decision Management space to bridge the gap between technical and business analyst: the Object Management Group published in 2015 the Decision Model & Notation, a specification for a graphical decision language, expressly designed for business users.
Drools provides an open source execution engine with full DMN support at conformance level 3. If you’re curious to know more about this there’s no better way than joining Phil Simpson and Denis Gagne in his free webinar on October 18 at 1pm ET where he will explore in details the features of this new standard.
