phases: software architecture and software design. in architecture, nonfunctional decisions are cast and separated by the functional requirements. in design, functional requirements are accomplished. software architerture architecture serves as a blueprint for a system. it provides an abstraction to manage the system complexity and establish a communication and coordination mechanism among components. · it defines a structured solution to meet all the technical and operational requirements, while optimizing the common quality attributes like performance and security. · further, it involves a set of significant decisions about the organization related to software development and each of these decisions can have a considerable impact on quality, maintainability, performance, and the overall success of the final product. these decisions comprise of − · selection of structural elements and their interfaces by which the system is composed. · behavior as specified in collaborations among those elements. · composition of these structural and behavioral elements …

siness risks associated with building a technical solution and builds a bridge between business and technical requirements. some of the other goals are as follows − · expose the structure of the system, but hide its implementation details. · realize all the use-cases and scenarios. · try to address the requirements of various stakeholders. · handle both functional and quality requirements. · reduce the goal of ownership and improve the organization’s market position. · improve quality and functionality offered by the system. · improve external confidence in either the organization or system. limitations software architecture is still an emerging discipline within software engineering. it has the following limitations − · lack of tools and standardized ways to represent architecture. · lack of analysis methods to predict whether architecture will result in an implementation that meets the requirements. · lack of awareness of the importance of architectural design to software development. …

· expert on available technologies that helps in the implementation of the system. · coordinate the selection of programming language, framework, platforms, databases, etc. methodological expertise · expert on software development methodologies that may be adopted during sdlc (software development life cycle). · choose the appropriate approaches for development that helps the entire team. hidden role of software architect · facilitates the technical work among team members and reinforcing the trust relationship in the team. · information specialist who shares knowledge and has vast experience. · protect the team members from external forces that would distract them and bring less value to the project. deliverables of the architect · a clear, complete, consistent, and achievable set of functional goals · a functional description of the system, with at least two layers of decomposition · a concept for the system · a design in the form of the system, with at …

ey are directly related to system’s architecture, design, source code, configuration, deployment parameters, environment, and platform. they are visible to the end-user and exist at runtime, e.g. throughput, robustness, scalability, etc. quality scenarios quality scenarios specify how to prevent a fault from becoming a failure. they can be divided into six parts based on their attribute specifications − · source − an internal or external entity such as people, hardware, software, or physical infrastructure that generate the stimulus. · stimulus − a condition that needs to be considered when it arrives on a system. · environment − the stimulus occurs within certain conditions. · artifact − a whole system or some part of it such as processors, communication channels, persistent storage, processes etc. · response − an activity undertaken after the arrival of stimulus such as detect faults, recover from fault, disable event source etc. · response measure − should …
