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’
