--caution: personal advert--:-)--
My (german) book "Enterprise Architekturen Leitfaden für effiziente Software-Entwicklung" is available now. It covers mostly topics from this blog. The idea of this webblog was actually to discuss some topics from the book and explain it more deeply. But I also misuse it from time to time to discuss issues, which I not fully understood :-).
I also deployed a dedicated homepage: http://e-architecture.info/ which will hopefully grow in the future. Your feedback is highly appreciated - just use this blog or send me an email: abien at adam minus bien dot com.
The funny story: I'm still waiting for a copy from the publisher :-).
