Worth a look - A process for MDD (Model Driven Development)

A post by lispy entitled "Why UML Fails to Add Value to the Design and Development Process" reminded me of an existing methodology put together by IBM.

Lispy wrote (I cut a lot out) -
"The modeling language must be a first-class citizen of the development process rather than just make-work for architects and project managers... There are two linguistic abstraction barriers that must be implemented in order to make this work: 1) the modeling language between the models and the generated code and 2) the framework between the generated code and the target libraries. You must build up from your core code components to the framework… and you must build down from the models to the generated code. If the code generation process is too complicated, you may need better abstractions at the framework level. If the code generation process is impossible, then the modeling language may not be providing a detailed enough description of the requirements. If there is too much repetition in the models, then the modeling language will need to be extended to cover additional concepts."


What I was reminded of was "Patterns: Model-Driven Development Using IBM Rational Software Architect", by the way you don't have to use IBM's products. You can go off and the whole thing, but chapter 4 is where the meat is and Figure 4.2 on pg 47 and the related descriptions on the following pages put it all in place. It really lays out a process which in my mind covers some of Lispy's concerns.

A short post just to share an interesting modeling process I learned about sometime ago.

Configuring Javascript SyntaxHighligher 3+ in a Blogger site

Image
In this post I tactically outline a quality way to configure the Javascript based SyntaxHighlighter library into a Blogger site. The configuration below makes use of the recent autoloader available in version 3 and greater of the SyntaxHighlighter.  The configuration code below is in fact using the SyntaxHighlighter which incidentally allows you to copy the code examples quickly.  Check out this very popular library here . Configuration: 1.  Login into blogger.com and click/select the site you want to configure ( http://www.blogger.com/home ) to support syntax highlighting.  Generally if there are multiple sites you would like to enable each site's template will need to be configured individually. 2.  Click the Template link from the sidebar of the Blogger Site main page shown below. 3.  Save the template, if you choose, by clicking on Backup/Restore in the upper righthand corner and following the instructions.  Better to be safe rather than sorry if you are not famil

Reference Cards, Cheat Sheets, Posters, whatever they are called.

Tonight I tried to find quick reference sheets for both UML and BPMN, free of course.  There are quite a fewer different terms for them be it poster, reference cards, cheat sheets, quick guides etc.  However, once I got into several sites by searching for "Reference Cards" I found the other names for these small printable guides to various technologies. Oh yes, and much more managable or likely to be used than " pocket references " which don't fit in your pocket. List of quality sites quick guides: refcardz.dzone.com itPoster.net (singular) cheat-sheets.org scribd.com/ (kind of) I did not find a suitable quality UML guide ( Stackoverflow has a list ), but the BPMN poster  at itPoster.net though outdated at time of this post was still really well done. There are several red herring links which get referenced a lot, but are not that good, ex: ( How are you to carry this around? ) Any other good sites that have a listing of printable reference guides?

The Technology Architect Organization Quiz - 7 questions to ask before taking the job

The Technology Architect Organization Quiz is a brief set of questions you should ask a potential employer during the interview.  In fact, you should always ask informed questions, after all that is a huge component of an architects job.  Getting a good idea of how a company views, structures, enables architecture is important as there is significant variety.  In some companies architects are looked to as strategic gurus, technology experts, but in others simply quality and design draftsmen, or worse Ivory Tower babblers.  The variety is compounded as there are differences between industries and between Europe and the US.  I have been refining the Technology Architect Organization Quiz for several weeks which and it is in the spirit of  The Joel Test  by Joel Spolsky.  I highly recommend checking out  The Joel Test  as it succinctly provides a good measure for development maturity while remaining simple yes or no questions.  I hope the Technology Architect Organization Quiz is just as
