What is DMN?

DMN (Decision Model and Notation) is a standard for modeling and automating decisions. It provides a common notation that is understandable by both business users and IT professionals, bridging the gap between business requirements and technical implementation. DMN models consist of decision requirements diagrams (DRDs) that define the dependencies between decisions, and decision tables that define the logic for individual decisions. It is commonly used in business rules management systems (BRMS) to automate and execute decision-making processes.
