This enables the visual specification of rules that can then be applied to a specific version of your code so that … Continue reading]]> http://www.headwaysoftware.com/blog/2009/11/mapping-architecture-diagrams-to-code-the-most-specific-pattern-rule/feed/ 0 http://www.headwaysoftware.com/blog/2009/03/travelin-lite/ http://www.headwaysoftware.com/blog/2009/03/travelin-lite/#comments Fri, 06 Mar 2009 09:40:59 +0000 Ian Sutton http://www.headwaysoftware.com/blog/?p=214 dzone_url = "http://www.headwaysoftware.com/blog/2009/03/travelin-lite/";Of course, you can’t code up a (meaningful) system without some number of building blocks. So even in a perfectly architected and layered system, you inevitably accumulate some baggage as you move up the stack. The trick, though, is to … Continue reading]]> http://www.headwaysoftware.com/blog/2009/03/travelin-lite/feed/ 2 http://www.headwaysoftware.com/blog/2007/08/package-design-matters-part-1/ http://www.headwaysoftware.com/blog/2007/08/package-design-matters-part-1/#comments Mon, 13 Aug 2007 09:16:54 +0000 Chris Chedgey http://headway.structure101.com/blog/?p=11 dzone_url = "http://www.headwaysoftware.com/blog/2007/08/package-design-matters-part-1/";Java packages are often used like file-system folders to organize source. But source files differ from “normal” files in that they are highly inter-dependent. Considering this interdependence as a package hierarchy evolves can have significant productivity benefits. Packages as Folders … Continue reading]]> http://www.headwaysoftware.com/blog/2007/08/package-design-matters-part-1/feed/ 1 http://www.headwaysoftware.com/blog/2007/08/spring-framework-21-m3-architecture/ http://www.headwaysoftware.com/blog/2007/08/spring-framework-21-m3-architecture/#comments Thu, 02 Aug 2007 06:35:53 +0000 Chris Chedgey http://headway.structure101.com/blog/?p=15 dzone_url = "http://www.headwaysoftware.com/blog/2007/08/spring-framework-21-m3-architecture/";Here are some architecture diagrams for Spring Framework 2.1 M3 (released yesterday).
