    Study Notes

    Software Architecture Definitions

    • Software architecture refers to the high-level design and organization of a system, including the relationships between components and data flow patterns.
    • Architecture embodies the fundamental organization of a system, its components, their relationships and the principles guiding design and evolution.
    • Software architecture is the high-level design and organization of software where important decisions are made regarding its overall structure, such as the relationships between components, data flow patterns, and the mechanisms for communication between different parts of the system.

    The Importance of Software Architecture

    • Architecture significantly impacts the system’s ability to exhibit desired quality attributes like performance, modifiability, security, scalability, incremental subset delivery, and reusability.
    • Architecture plays a crucial role in managing change by partitioning possible changes into three categories: local, nonlocal, and architectural changes.
    • Architecture defines constraints on implementation by prescribing the elements, their interaction, and responsibilities.
    • Architecture influences the organizational structure by providing the basis for the work-breakdown structure, dictating planning, scheduling, and budgetary units as well as inter-team communication, configuration control, integration, and testing procedures.
    • Architecture facilitates evolutionary prototyping by enabling analysis and prototyping of a skeletal system.

    Life-Cycle Activities

    • Software architecture design is a key activity in the software architecture life-cycle, concerned with translating requirements into a design and implementation.
    • Architecturally significant requirements (ASRs) include functionality, constraints, and quality attributes guiding the selection of architectural structures.
    • Architectural design is a translation from the world of needs (requirements) to the solution world, using code, frameworks, and components.
    • Architectural documentation creates a formal document from sketches or preliminary documentation of the structures.

    The Role of the Architect

    • The architect defines and designs the software architecture, selects appropriate technologies, frameworks, and patterns.
    • The architect collaborates with stakeholders to understand their needs and requirements, ensuring the architecture aligns with project goals.
    • The architect ensures scalability, maintainability, and security by making high-level design choices and setting technical standards.
    • The architect provides technical leadership and guidance to development teams, mentoring less experienced developers.
    • The architect evaluates and selects third-party tools, libraries, and platforms considering factors such as cost, performance, and compatibility.
    • The architect identifies and addresses technical risks and challenges, proactively assessing the architecture to identify potential issues and devising mitigation strategies.
    • The architect creates and maintains comprehensive software architecture documentation.
