    Study Notes

    Fundamentals of Software Architecture

    • Definition: Software architecture refers to the high-level structures of a software system, including its design and documentation.
    • Architecture emphasizes development, algorithms, data structures, communication, and the arrangement of system components.
    • Captures three primary dimensions: structure, communication (behavior), and nonfunctional requirements.
    • Essential for establishing a system's foundational design from software requirements into a collection of design elements.

    Importance of Software Architecture

    • Acts as a critical step in software development, not merely as documentation through reverse engineering.
    • Quality considerations must be integrated during architectural design to ensure system quality.
    • Architecture lays the groundwork for meeting both functional and non-functional requirements.

    Key Tasks in Software Architecture

    • Identify stakeholder concerns: Engage with groups or individuals impacted by the software, such as engineers and project managers.
    • Determine architectural views: Different perspectives are needed for evaluating the system based on stakeholder roles.
    • Explore architectural styles and patterns: Utilize reusable design strategies that have a history of success.
    • Define major system components and interfaces: Recognize essential parts and how they interact.
    • Evaluate and validate architecture: Conduct iterative assessments to catch defects early in the process.
    • Establish design synchronicity policies: Ensure ongoing alignment between implementation and design throughout software development.

    Stakeholders' Concerns and Quality Attributes

    • Concerns should guide architectural decisions and reflect desired system characteristics.
    • Important quality attributes include usability, modifiability, security, performance, reliability, portability, testability, availability, and interoperability.
    • Quality attributes should be translated into actionable design tactics to influence software behavior and structure.

    Architectural Design Tactics

    • Usability: Design decisions like providing 'undo' and 'cancel' options enhance the user experience.
    • Security: Implement measures such as user authentication and limited access to protect data.
    • Testability: Include event logging to facilitate testing processes.
    • Modifiability: Encourage modularization and encapsulation to isolate changes.
    • Availability: Use redundancy and monitoring to ensure system uptime.
    • Performance: Focus on computational efficiency and introduce concurrency where possible.

    Architectural Views

    • Different perspectives must be represented in architecture to address the varied concerns of stakeholders and assess specific system attributes.
    • An architectural view is a distinct representation that helps evaluate properties relevant to particular stakeholders.

    Evaluating and Validating Architecture

    • The evaluation process should be long and iterative to adjust designs as needed and address flaws early.
    • It's crucial to determine if the architecture sufficiently meets the system's development needs.

    Design Synchronicity

    • High design synchronicity indicates a strong alignment between design and implementation.
    • A successful architectural effort requires synchronized processes throughout all development stages and phases.

    Problem-Solving in Architecture

    • Architecting involves balancing constraints like schedules, costs, and quality against system requirements and goals.
    • Documentation and collaborative evaluations are essential in addressing the complexities of design.
    • Design activities, such as architectural reviews, should be scheduled and performed with planned anticipation and presence of relevant stakeholders.

    Summary

    • The session discussed the core concepts of software architecture along with key tasks like stakeholder identification, architectural views, and evaluation processes.
    • Understanding these fundamentals will pave the way for the next focus on requirements engineering essential for developing robust software systems.
