The DMN Pocket Reference provides in-depth explanations of the DMN elements using easily comprehensible diagrams. The DMN Pocket Reference defines the DMN elements contained in a decision model diagram, as described in the Object Management Group (OMG) specification. The notations are clearly portrayed using graphical diagrams showing how they are depicted, each with a brief description. Examples have been included to demonstrate the use and implementation of the DMN notations. The DMN Pocket Reference also illustrates the link between DMN, Decision Logic and BPMN.
