Graphical programming (what these round trip tools promise to be able to do) does not work. The mere fact that you need to have every part of the code in the diagram leads to diagram overload. One of the important tasks when creating diagrams (not only UML) is to select what needs to be shown and how it needs to be shown. This is something a human needs to do. It cannot be automated. Normally to understand a system only a few classes need to be depicted and not with every detail (method, data member etc.). Updating diagrams with every changed detail is tedious and useless because it does not improve understanding. Often the basic relationships between classes remain the same because they are at the heart of the design. And btw., roundtrip tools don't help much with updating diagrams which are sitting in text documents. That still has to be done manually - unless someone invents a system which manages everything (code and documentation). But then it would still need a human being to decide whether a new sub class should show up on a particular diagram or not. My preferred tool is Visio with the free available set of UML stencils. This makes creating UML diagrams easy (because all the elements are there) but retains enough flexibility to mix in other information as needed. > Still, as others already mentioned, it is convenient to have a common > design language that is not implementation specific, and that is known by > most programmers out there.

When I have to, I use Umlet to persist them too. I use these diagram types in decreasing (estimated) frequency: - class - activity - state - sequence rarely: - object - deployment Kind regards robert -- remember.guy do |as, often| as.you_can - without end http://blog.rubybestpractices.com/
