1. The Omondo EclipseUML plug-in David Gallardo

2. What is UML A graphical language Not a development method It was designed for RUP—the Rational Unified Process, but it supports other methods Popular for agile and XP programming Not a visual programming, but some tools can generate code based on diagrams, especially class diagrams

3. Omondo Eclipse UML Two versions: –Free edition includes comprehensive UML support. –Studio edition adds J2EE support (including visual deployment diagrams, visual assembly of EAR, WAR and EJB jar files) and database support. Free version is limited to a single user per project in a commercial environment

4. UML diagrams supported Class diagram (with live sync between diagram and Java code) Sequence diagram Use-case diagram Statechart diagram Collaboration diagram Activity diagram Object diagram Component diagram Deployment diagram

5. Which diagrams to use? Different types of diagrams are useful in different environments Learn a few, incorporate into development process & expand as you see a need Class diagrams and (especially) use case diagrams are popular for Agile/XP programming We’ll only look at use case diagrams and class diagrams in this demo.

6. Use case diagrams Stick figures represents actors in a scenario This may seem a little silly at first, but it makes the use case clear, and it’s valuable, especially for Agile programming because non-techie users can understand easily provide valuable feedback

7. Class diagrams Serve different purposes, informal and formal Can represent: –Conceptual view of a set of classes –Form a specification –Describe implementation Conceptual view is useful as conversational tool –Don’t need to show all relationships—you might show all inheritances but only show associations when they are particularly meaningful –Don’t need to be too strict about following UML rules
