Description

Objects in the model have defined relationships with each other that establish an explicit knowledge graph of the system being modeled. These relationships are either unidirectional (in and out) or bidirectional (inout) and can be traversed by the user while exploring the model. A summary of the existing relationships in Davinci are dicussed below:
Relationships must be given a Relationship Type when created. Select the Relationship Type, then the Relationship Object when creating a new Relationship
