Dynamic Relationships

The dynamic relationships describe temporal dependencies between elements within the architecture. They are often mistakenly interpreted as causal relationships implying that the element at the tail end of the relationship somehow causes the element at the arrow end to 'fire' - this is not correct. In the case of the Flow relationship an item can be transmitted between the two connected elements. Two types of dynamic relationship are distinguished as indicated in this table.

Dynamic Relationships

Triggering

The triggering relationship represents a temporal or causal relationship between elements.

Flow

The flow relationship represents transfer from one element to another.
