Quality-Driven Architecture Design Method

چکیده
In this paper we introduce a quality-driven architecture design (QAD) method with three phases: system analysis, conceptual architecture design and design of a concrete architecture. Architecture design phases produce an aspect of software architecture at two different levels of abstraction. System analysis provides a bigger picture of the software system and its properties. Conceptual architecture organises these functional and quality responsibilities into conceptual elements, while a concrete architecture describes hierarchical components and communication protocols between them. Architectural descriptions at both abstraction levels are defined from three viewpoints: structural, behaviour and deployment. The QAD method has been applied with in a case study of a distributed service platform with the mobility of system services.

The final quality and cost of a manufactured product are determined to a large extent by the engineering design of the product and its production process through activities of off-line quality control methods, namely, System Design, Parameter Design and Tolerance Design. However, in the context of most non-industrialized countries, the off-line quality activities of product design and system de...
متن کاملModel Driven Design Method for Software Architecture
Software Architecture allows for early assessment of and design for quality attributes of a software system. It provides an important help for current software development. The development of software architecture is complex due to the absence of a standard way that lead the generation of software architecture artifacts. In this paper we define an architecture design method that provides the sy...
متن کاملQuality Attribute Design Primitives and the Attribute Driven Design Method
This paper discusses the understanding of quality attributes and their application to the design of a software architecture. We present an approach to characterizing quality attributes and capturing architectural patterns that are used to achieve these attributes. For each pattern, it is important not only how the pattern achieves a quality attribute goal but also what impact the pattern has on...

Software integration in distributed architecture plays an important role to improve software quality. Engineers often face challenges coming from connectors. Especially, design of connectors in a distributed system encounters more design issues such as: i) how to fulfil the functional and quality requirements of connectors in distributed system; ii) how do multiple technologies combine together...
متن کاملQuality-driven architecture design and quality analysis method A revolutionary initiation approach to a product line architecture
The role of software architecture has changed. The use of modern software technologies and practices enables turning the focus of system development to the quality aspects of software instead of functional properties. Architecture addresses the quality issues of software and, therefore, it must be developed and documented properly. In particular, there is a need for high level architectural des...
