Pimp My Diagram
The Pimp My Diagram series discusses some issues in UML sequence diagrams and shows you how to improve your own diagrams.
Each episode features the makeover of a single sequence diagram, either picked from the web or submitted by a reader.
Episode 1 - Seagull (s01e01)

The original UML sequence diagram
The chosen diagram depicts a typical process flow in the open source Seagull PHP framework : controller intialization, processing and page rendering.

How it was done
The original diagram was recreated and improved using Trace Modeler, the easy-to-use and smart UML sequence diagram editor.

Ok, that concludes the commercial break, on with the show!
The improved UML sequence diagram
The goal of this article is to improve the original sequence diagram without changing the actual interaction that it depicts. The improvements are purely based on the diagram itself, I am not familiar with the Seagull framework (nor with PHP for that matter). So if you are Seagull-savvy, you may be able to take it even further.
The actual makeover of the diagram will be done in two phases
- Phase 1 : improve the diagram content
- Phase 2 : split the large diagram into parts
Here is a pimped version of the diagram after phase 1 (click to enlarge)
If you want me to pimp your diagram or have seen an interesting one somewhere, send it to me and I'll try to feature it in an upcoming article!
