Das Zachman Framework ist ein 1987 von John Zachman konzipierter domänenneutraler Ordnungsrahmen zur Entwicklung von Informationssystemen.
Es bildet dabei einen Leitfaden, der Vorschläge enthält, welche Aspekte aus welchen Perspektiven Berücksichtigung finden sollten, um die IT-Architektur einer Unternehmung erfolgreich aufzustellen. Mit Hilfe dieser Modellierung kann sowohl die Dokumentation- als auch die Planung eines solchen Projekts unterstützt werden, wenn bspw. nachvollzogen werden soll, welche Entscheidungen welche technischen Umsetzungen nach sich gezogen haben.
The Zachman Framework is a framework for enterprise architecture, which provides a formal and highly structured way of viewing and defining an enterprise.
The Framework in practice is used for organizing enterprise architectural "artifacts" in a way that takes into account both:
who the artifact targets for example, business owner and builder, and
what particular issue for example, data and functionality is being addressed.
These artifacts may include design documents, specifications, and models.[3]
The Framework is in essence a matrix,[4]. It is named after its creator John Zachman, who first developed the concept in the 1980s at IBM. It has been updated several times ever since.[5]
Today 206 years ago, engineer John Augustus Roebling was born. He was best known for the design of the Brooklyn Bridge. Sadly Roebling passed away 14 years before the famous bridge in New York City was opened.
XRX is a new web development architecture that is a milestone in elegant simplicity. XRX stands for: XForms on the client REST interfaces and XQuery on the server Because XRX uses a single model for data (XML) it avoids the translation complexity of other architectures. The simplicity and elegance of XRX allows developers to focus on other value-added features of web application development and enables non-programmers to create a rich web interaction experience without the need to use procedural programming languages.

As a portal and platform for good architecture, world-architects.com is the first address for realty developers and private builders who want to do more than just build houses. Our distinctly individual profiles highlight successful, well-established architectural firms, exciting projects by young architects, as well as ambitious landscape designers, engineers, photographers, and light designers
Woophy stands for WOrld Of PHotographY, a website founded by a Dutch collective of photo aficionados and internet designers who believe navigation on internet can be more visual, logical and associative. The goal of Woophy's founders is to create an accessible, visual, current, democratic and collective work of art comprised of a database picturing our remarkable world.
This post takes a look at the speed - latency and throughput - of various subsystems in a modern commodity PC, an Intel Core 2 Duo at 3.0GHz. I hope to give a feel for the relative speed of each component and a cheatsheet for back-of-the-envelope performance calculations. I’ve tried to show real-world throughputs (the sources are posted as a comment) rather than theoretical maximums. Time units are nanoseconds (ns, 10-9 seconds), milliseconds (ms, 10-3 seconds), and seconds (s). Throughput units are in megabytes and gigabytes per second. Let’s start with CPU and memory, the north of the northbridge:
The above diagram is a fairly good representation of our architecture at Storyblocks. If you’re not an experienced web developer, you’ll likely find it complicated. The walk through below should make…

A. Ferscha, G. Kathan, und S. Vogl. The Eleventh International World Wide Web Conference, Honolulu, Hawaii, USA, (2002)The WebWall is a system which enables multi-user communication and interaction via shared public displays and the pervasive and seamless access to the WWW in public areas via e.g. mobile phones or handheld devices. In this project, the concept for a WebWall has been elaborated and a software framework for the operation of WebWalls has been developed, By employing a strict separation of WebWall I/O technologies (like HTTP, email, SMS, WAP, EMS, MMS or even simple paging protocols found on mobile phones) from the underlying framework architecture, the physical display technologies used and the presentation logic involved, the system enables access for a range of devices.
The architecture integrates ubiquitous wireless networks (GSM, IEEE802.11b), allowing a vast community of mobile users to access the WWW via public communication displays in an ad-hoc mode. A centralized backend infrastructure hosting content posted by users in a display independent format has been developed together with rendering engines exploiting the particular features of the respective physical output devices installed in public areas like airports, train stations, public buildings, lecture halls, fun and leisure centers and even car navigation systems. A variety of different modular service classes has been developed to support the posting or pulling of WWW media elements ranging from simple sticky notes, opinion polls, auctions, image and video galleries to mobile phone controlled web browsing..
