Forthcoming

• work-in-progress: Grady Booch is working on a Handbook of Software Architecture, that, we are told, will document a number of software architectures. See http://www.booch.com/architecture/index.jsp

Architecture Diagrams

• Booch has a "gallery" of architecture diagrams that he has collected from various sources.
• Try searching on "software architecture" in A9 (Amazon's search engine) and check out the 21,100 images that come up! Just kidding, but do check out some of them! It is rather a hunt-and-peck search because all kinds off stuff shows up.

Contributions to this Webpage

Please let Ruth Malan at Bredemeyer Consulting know if you know of case studies and architecture project deliverables or artifacts so that we can make this web page more comprehensive and useful.

Note on URLs

I provide both a link on the case study name and the URL. I realize, naturally, that when one is online, the URL is superfluous, and indeed often very ugly. Sorry about that. But as soon as the page is printed, the links do not show up as URLs, of course. Yes, I know one could "Google" the title and find the referenced work even more easily than typing in an arcane URL. It is a matter of reference—the URL identifies exactly where the referenced work (at least at some point) was published online. I believe that the "old establishment" are going to have to recognize the legitimacy of papers published on the web, and create a standard for referencing them. If/when such a standard exists, please do inform me of it! Until then, I think it is reasonable to be complete in referencing the URL as the publication source.
