Architecture is influenced by organizational factors, market forces, and technology that are constantly changing. We found that successful architects analyze factors that have a global influence to produce an architecture that localizes the effects of change. Change is a fundamental property of all factors that influence the architecture. To account for the influence of change we identified a g...

Currently, information architects create metadata category hierarchies manually. We present a nearly-automated approach for deriving such hierarchies, by converting the lexical hierarchy WordNet into a format that reflects the contents of a target information collection. We use the term “nearly-automated” because an information architect should have to make only small adjustments to produce an ...

This paper presents a non-technical overview of the the recent attacks against RSA encryption and signature standards. It is intended as both a system design aid and a temporary reference text beginning at a level suitable for engineers, risk managers and system architects with no or little previous exposure to padding attacks. We have used a straightforward approach to the essential consequenc...

Rigorous modelling techniques and specialised analysis methods support enterprise architects when embarking on enterprise architecture management (EAM). Yet, while customised modelling solutions provide scalability, adaptability and flexibility they are often in conflict with generic or reusable visualisations. We present an approach to augment customised modelling with the techniques of model ...

Traditionally, architects and designers have worked with clients to develop and implement design solutions from both a functional and an aesthetic approach. The functional approach is justifiable from user needs and activities assessment studies as well as programming data. Aesthetic approaches to the built environment are typically realized through the thoughtful selection of materials, color,...

This paper proposes a static software architecture verification approach based on a dependency constraint language that allows software architects to restrict the spectrum of dependencies that can be present in a given software system. The ultimate goal is to allow the definition of acceptable and unacceptable dependencies according to the planned system architecture. Once defined, such restric...

• Familiarity with structural concepts and systems • Familiarity with mechanical and other building service systems... architects and engineers can expect that a ...

Fully exploiting the potential of on demand computing requires on demand business models. To respond “on demand” to the unpredicted opportunities of the moment, a business must invest in knowing earlier the meaning of what is happening now rather than in attempting to forecast better the opportunities of the future. This means concentrating on know-why, which is system knowledge, rather than kn...
