Study Notes
Software Architecture Overview
- Architecture represents the structure and organization of a software system, distinct from operational software.
- Enables evaluation of design effectiveness, exploration of alternatives, and risk reduction in software construction.
Importance of Software Architecture
- Facilitates stakeholder communication regarding system development.
- Early design decisions impact subsequent engineering efforts significantly.
- Provides a graspable representation of system structure and component interactions.
Architectural Descriptions
- IEEE-Std-42010-2011 outlines architectural viewpoints, frameworks, and descriptions.
- Architectural descriptions must identify stakeholders' concerns like system purpose, risks, and maintainability.
Architecture Decision Documentation
- Essential information for decisions must be determined and linked to requirements.
- Acknowledge relationships among decisions to ensure traceability.
- Evaluate data flow modes and interactions between functional and data components.
Architectural Considerations
- Economy: Focus on simplicity and abstraction.
- Visibility: Clarity in architectural decisions and justifications for engineers.
- Spacing: Clear separation of concerns with minimal dependencies.
- Symmetry: Balanced and consistent system attributes.
- Emergence: Promote self-organizing system behavior for scalability.
Architectural Design Process
- Define external entities the software will interact with and their interactions.
- Identify software archetypes representing system behavior elements.
- Specify component structures that follow identified archetypes.
Architectural Tradeoff Analysis
- Gather scenarios and elicit requirements for evaluations.
- Describe chosen architectural styles/patterns and assess quality attributes.
- Analyze sensitivity of quality attributes to architectural styles.
Component-Level Design Steps
- Define attributes and data structures for components.
- Describe processing flows within operations.
- Identify persistent data sources, databases, and related classes.
- Factor designs and explore alternative implementations.
Web App Component Design
- Defined as cohesive functions or packages providing user capabilities.
- Incorporates content and functional design elements.
Mobile User Interface Evaluation
- Assess consistency across applications and device interoperability.
- Consider stakeholder values and user expectations in the target market.
Mobile Design Approaches
- Usage scenarios must account for context variables and transitions.
- Ethnographic observation captures natural user interactions with products.
- Low-fidelity prototypes facilitate usability assessments pre-development.
Common Mobile Design Mistakes
- Avoid feature bloat and maintain uniformity in design standards.
- Streamline designs by removing unnecessary elements.
- Ensure quick loading times and recognize the user's existing experience.
- Correct poor design rather than relying on help features for user guidance.
Services Computing
- Focuses on architectural design for service discovery and application development.
- Allows mobile developers to avoid integrating service source code into apps.
