What UML is● A language to describe what elements in an
image mean● intended to provide a standard way
to visualize the design of a system
What UML is not● A software analysis methodology● A software design methodology● A programming language● Free from dialects and heated debates
UML False Promises● Design and code are interchangeable
– a.k.a. “reverse engineering”– a.k.a. “round-trip engineering”
● Easily generate your code from the design– Every MDD tool needs additional work/code– ‘Glue code’ tends to be painful
● Fool-proof– No, fools still make beautiful but bad designs
● Time saving

PlantUML
PlantUML Demo
● Turn simple text into UML diagrams
● Microsoft Visual Studio Code on Linux– with PlantUML plug-in– This Plug-in uses a web service for rendering
● Available stand-alone as jar file
The Use Case
Key take aways:
PlantUML is:● Quick Text-to-UML-Diagram tool
● Made for programmers; not for “powerpoint architects”
● Simple, versatile and “good enough”
● Text-based: store files in your repo!
● Available as plug-in for almost everything
● Just as annoying when it ‘won’t align properly’
