Gallery of UML sequence diagrams
Example from 'Pattern-Oriented Software Architecture', MVC scenario 1
This UML sequence diagram is one of the examples included in the Trace Modeler distribution.
It was reproduced from 'Pattern-Oriented Software Architecture' by F. Buschmann et al. The diagram style of the book has been matched as closely as possible. Note how the labels on messages are aligned with the receiver in this diagram (usually authors align them with the caller).
The bitmap was created by exporting the file 'from book posa mvc scenario 1.trace' in the examples folder of your installation, at 72dpi and 100% scale in png format.
