Trace is a kind of dependency that indicates a historical relationship between two elements that represent the same concept at different semantic levels or from different points of view. The related elements abstract the same part of the system but in different models. The notation for a trace dependency is a dashed arrow labeled with the stereotype <<traces>>.
