In the last article of this series, we provided an overview of ArchiMate Concepts that symbolized artifacts that make up TOGAF’s Architecture Framework. Each of the concepts has specific relationships to each other that represent flow, dependencies, realizations, and others. Relationships usually have specific pairings, but not always.
Consider the following diagram:
Structural Core Relationships
Association: Models a relationship between objects that is not covered by another, more specific, relationship. Often used when the relationship is not known or is not relevant to a viewpoint.
Realization: Links a logical entity with a more concrete entity that realizes it; that is, a logical representation of a real object (a data object is real; a report is the logical entity that is realized by the data object).
Aggregation: Indicates that an object groups a number of other objects. Objects can be aggregated to more than one aggregating object. Composition: Indicates that an object is composed of one or more other objects. The latter objects can only be part of one composition.
Flow: Describer the exchange or transfer of, for example, information or value between processes, function, interactions, and events.
Grouping: Indicates that objects of the same or different types belong together based on some common characteristics.
Motivation relationships deal with interaction/dependencies between motivation concepts such as drivers, goals, principles, etc. Two of the relationships are similar to Core relationships but have different connotations: Aggregation and Realization. The influence relationship is unique to Motivation.
Aggregation: Models the division of some intention into multiple intentions (arrowhead points to the more general, undivided intention).
For the next blog entry, we will demonstrate how Concepts and Relationships are combined to create Viewpoints and other visualizations.
