Recently I have been reverse engineering a state transition (officially a state machine but I prefer the term state transition model) to understand the complex life-cycle of our application’s central object. I had seen a demo on model simulation but the focus was more on a generated model from source rather than a hand fashioned UML model. This post is a walk through on the process and hopefully some takeaways from what I’ve learned. Understanding complex systems I came into a project that is well down the road to completion but sorely lacking in any concrete documentation which was becoming…
I wanted to share a tip that I've been using for a while that seems to be a reason some people give for not liking Enterprise Architect (EA) – not being able to track document changes. EA works by generating RTF documents of its content which many users prefer of the more interactive HTML renderings of that same content – either due to habit or function. While EA has countless benefits for analysis (just read this blog for many examples!) it doesn't provide document versioning / differencing out of the box. This is no problem at all since MS Word…

Colour your Knowledge

Written by
Colouring your EA models isn't just a matter of making your diagrams pretty. Colour can add clarity and accuracy to your models, and make it easier for the consumers of you knowledge to understand what you mean. This paper reviews some of the ways you can use colour, to show structure and status in your EA Models, and provide guidance and insight for specific groups of users.

Four Principles of Agile Triage

Written by
There’s an epidemic of bad software floating around these days. Chances are you’ve encountered buggy and/or unnecessarily hard to use software recently. This epidemic isn’t really surprising, especially if you’ve read the books I’ve written with Matt Stephens: Design Driven Testing or Extreme Programming Refactored or Agile Development with ICONIX Process. There’s a bunch of agile development shops out there underspecifying their software and (as a result) testing it inadequately, so that you and I can have the privilege of debugging it for them and putting new user stories onto their backlog. Imagine for a moment that you’re working at…
Using an external source code editor Sparx Enterprise Architect can be configured to open source files in an external editor. This is good news for developers who already have a strong preference (and keyboard skills) for using a particular editor, such as Vim or EMACS. Working inside Sparx Enterprise Architect: Click Tools | Options...   The Options window is displayed. Click Source Code Engineering | Code Editors.   Clear the check-box alongside Use inbuilt editor if no external editor set, and then click Close.   Right-click an UML class element (in the Project Browser or on a diagram), and select View Source Code...   The source code will displayed in an external editor window,…
Morgan Kauffmann has published the second edition of “A Practical Guide to SysML” by Sanford Friedenthal, Alan Moore and Rick Steiner (ISBN 978-0-12-385206-9). The authors have made a very complete selection of supporting materials available for download from http://www.elsevierdirect.com/v2/companion.jsp?ISBN=9780123852069. These companion resources include the “Air Compressor”, “Automobile”, “Distiller”, and “Security System” example models, as described in the book. Unfortunately, the model files are only available in MagicDraw tool format (although the authors have also provided HTML reports for use by anyone who do not have access to MagicDraw). I decided to try importing the files into Sparx Enterprise Architect version…
In any given system under development, the business domain of that system is key. It holds all concepts important to the domain, and captures the business logic from the domain. An important question to answer is what to model about the objects in that domain and how to model this in UML class diagrams. This tutorial shows you how can achieve this, using Enterprise Architect. http://sanderhoogendoorn.com/blog/?p=1045

Do Androids dream of UML models?

Written by
Reverse Engineering the Android SDK with Enterprise Architect Recently one of our Senior Conulstants here at DT (Colin Coates) thought it would interesting to use Enterrprise Architect to reverse engineer the Android version 1.6 SDK (as used in the brilliant Google Nexus 7 tablet) into a UML model. He started the process by clicking the menu: Tools > Source Code Engineering > Import Source directory… Colin then used the following settings in the Import Source Directory (dialog) window: Source Type = Java (of course!) Recursively Process Subdirectories Create Logical Diagram for Each Package Create Package per Namespace (in the Package…
Using Enterprise Architect in a Team Environment often involves a version control repository like SVN (Subversion). This article describes a way to compare the current version of a package in your model, which is controlled under an XMI file in SVN, with an older version of this package. This is achieved through the use of the EA Baseline feature.
Running EA on a Server can be very helpful for Integration or Build Server Purposes. In an older Blog Post we documented how to do it for Windows 2003 Server - this way doesn't work any more. In Windows Server 2008R2 Microsoft introduced Session-0 security – easy explanation: so it becomes much harder for interactive service to run as Local System and interact with users. If you want to run EA (an interactive app) as an unattended Windows Service (as an interactive service) you have to do some strange steps to achieve it. Follow the Version 1.0 of the attached…
