Module: Archimate::DataModel::Relationships

Defined in:

lib/archimate/data_model/relationships.rb

Overview

Relationship Classifications: Structural, Dynamic, Dependency, Other

• No relationships are allowed between two relationships

• All relationships connected with relationship connectors must be of the same type

• A chain of relationships of the same type that connects two elements, and is in turn connected via relationship connectors, is valid only if a direct relationship of that same type between those two elements is valid

• A relationship connecting an element with a second relationship can only be an aggregation, composition, or association; aggregation or composition are valid only from a composite element to that second relationship

Aggregation, composition, and specialization relationships are always permitted between two elements of the same type, and association is always allowed between any two elements, and between any element and relationship.

Defined Under Namespace

Classes: Access, Aggregation, AndJunction, Assignment, Association, Composition, Flow, Influence, OrJunction, Realization, Serving, Specialization, Triggering
