● 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 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 A few visual UML tools

● 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’
