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.
