Many claim that software systems must be designed for security. This, however, is far from being an easy task, especially for complex systems. We believe that this difficulty can be alleviated by a set of —preferably rigorous— principles. We propose an architectural style, the Dual Protection Style (DPS), for constructing secure software. This style results from our experience in designing and ...

This paper presents an evolutionary approach to style emergence in architectural designs. Emergence is the process of making features explicit which were previously only implicit. Style is considered as a set of common characteristics of a group of designs. It is interpreted using a language model as an analogy and is represented at the genetic level. An evolutionary system based on genetic eng...

A product-line is a set of software systems sharing the same architecture and implementation platform. Based on an analysis of several industrial product-lines, a general layered model is proposed as the main structuring principle of a product-line. It is demonstrated that the model can be used to explain and clarify several existing product-line architectures.

These days, a large percentage of software development is on the web and for the web. “Web services will become the predominant method for making information and applications available programmatically via the Internet in the near future” [9]. And in that context, one of the most important and resource consuming activities in the e-commerce industry today is the "webenablement" of existing soft...

Applications with run-time changing architectures constitute a challenge for both modelling and reasoning. Their description is not limited to the specification of a unique static topology but must cover the scope of all the correct configurations. We develop, in this paper, the concept of architectural styles to achieve this goal. We elaborate and specify the basic architectural styles for the...
