Architectural patterns(styles) are important artifacts containing specialized design knowledge to build good-quality systems. Complex systems often exhibit several architectural patterns in their design which leads to the need of architectural pattern composition. Unfortunately, information about the composition of patterns tend to be vaporized right after the composition process which causes p...

This paper presents a quality-driven software architecture design method. The method produces architectural descriptions at two levels of abstraction. Both the levels are described using four similarly named views: structural, behavior, deployment and development. More importantly, the method enables the realization of quality attributes by means of quality requirements and quality scope, which...

In this paper, we present a pattern-based software development method that preserves usability and security quality characteristics using a role-driven mapping of requirements analysis documents to architectural design artifacts. The quality characteristics usability and security are captured using specialized problem frames, which are patterns that serve to structure, characterize, and analyze...

The problem of formalizing architectural styles has been recently tackled with the introduction of the concept of architectural type. The internal behavior of the system components can vary from instance to instance of an architectural type in a controlled way, which preserves the absence of deadlock related architectural mismatches proved via the architectural compatibility and interoperabilit...

In this paper, we present an architecture-based approach for modeling software reliability. Our approach aims at modeling reliability on various software infrastructures and in any stage of software life cycles. To this end, we utilize characteristics of architectural styles to capture non-uniform behaviors of software embodying heterogeneous architecture. Furthermore, a state model that synthe...

Services computing research and practice traditionally has focused on the objectives of business alignment, software systems interoperability and on leveraging the Web as a compute platform. Corresponding technology solution stacks and architectural styles have been promoted. Today, and probably for the next decade to come, different objectives are replacing these original ones and, correspondi...

When designing software architectures, an architect relies on a set of pre-defined styles commonly named architectural patterns. While architectural patterns embody high level design decisions, an architectural tactic is a design strategy that addresses a particular quality attribute. Tactics; in fact, serve as the meeting point between the quality attributes and the software architecture. To g...

The synthesis of the three-dimensional morphology of a building is one of the most important tasks in architecture. Space planning and morphology are of the most interesting and complex of architectural design problems. Architectural design is guided by the constraints on the spatial composition and the morphology of the final building. During the conceptual phase problems are characterised by ...

This work proposes an architectural style, a pattern, for SDIs. This style provides a tool and a shared vocabulary to help system architects to design these infrastructures, and facilitates the exchange of knowledge about them. This style is defined under the component-andconnector architectural viewtype, extending the client-server and shared-data styles. The style has been created after analy...
