Architecture definition requires architects who are highly qualified in both the use of architectural patterns and the analysis of the application's requirements. This is because they have to identify what patterns satisfy the application's functional requirements (FR) and quality attributes (QA), and the interrelationships between them. However, since QAs and FRs are usually addressed separate...

An important way that the reliability of a software system is enhanced is through the implementation of specific run-time measures called runtime tactics. Because reliability is a system-wide property, tactic implementations affect the software structure and behavior at the system, or architectural level. For a given architecture, different tactics may be a better or worse fit for the architect...

today, mass media act like a magic mirror, not only reflecting the reality of societies, but also projecting a variety of images onto people’s thoughts. because of this great ability to produce, reproduce and disperse images, mass media have acquired considerable influence on people’s lives. among the different media, the television in particular has become an inseparable part of most iranian h...

Software architecture is a standard and essential part of system development. The knowledge produced and consumed during this process needs to be shared and reused among different stakeholders. Therefore, software architecture knowledge (AK) needs to be managed for improving the architectural capabilities. ADUAK (Architectural Development using Architectural Knowledge) model has been developed ...

This paper presents a quality-driven approach to embodying non-functional requirements (NFRs) into software architecture using architectural tactics. Architectural tactics are reusable architectural building blocks, providing general architectural solutions for common issues pertaining to quality attributes. In this approach, architectural tactics are represented as feature models, and their se...

Software architecture is considered one of the most important indices of software engineering today. Software Architecture is a technical description of a system indicating its component structures and their relationships, and is the principles and rules governing designing. The success of the software depends on whether the system can satisfy the quality attributes. One of the most critical as...

Security, as an architectural quality, is often thought to be measured in terms of availability, confidentiality and integrity. These qualities are part of a broader quality dependability. There are inherent tradeoffs among the qualities that define security and dependability. Architectural tactics, or architectural design decisions, that enhance one aspect of dependability can decrease securit...

Introduction Business critical software systems have to be maintained for a long time in order to conserve their business value and for the constant provision of business services. However, frequent changes due to enhancements, business process optimization, or technological improvements have to be performed. As a consequence, evolvability and variability of software systems constitute importan...

Today, one of the important topics, which are mentioned in architecture, is the relationship between architectural works with each other and way of effect of such works on them. On the other hand, under current conditions and despite existing trends which look for their own architecture, it is crucial important to interpret how contemporary architectural works are affected by previous architect...

Currently, the requirements of Business sector promote more and more complex Information Systems. Reliability is one of the quality characteristics widely expected by users and developers. This characteristic is architectural by nature since it can be directly promoted by software architecture. This relation determines the importance of designing architectures that guarantee reliable systems. T...
