Study Notes
Software Architecture Definition and Importance
- Software architecture is the set of structures needed to reason about the system, comprising software elements, relations among them, and properties of both.
- Architectural design involves making decisions to transform design purpose, requirements, constraints, and architectural concerns into structures.
- These structures guide the project, including analysis, construction, cost and schedule estimation, team formation, risk analysis, and implementation.
Issues in Architectural Design
- Architectural requirements, including how components are distributed and communicate with each other, and what technologies to use.
- Key issues to consider: scalability, performance, and change frequency.
Importance of Software Architecture
- Enables reasoning about and managing change as the system evolves.
- Allows early prediction of a system’s qualities.
- Enhances communication among stakeholders.
- Carries the earliest and most fundamental design decisions.
- Defines constraints on subsequent implementation.
- Influences the structure of an organization.
- Can provide the basis for evolutionary prototyping.
- Key artifact for reasoning about cost and schedule.
- Can be created as a transferable, reusable model.
Software Architecture Views/Perspectives
- Logical View: concerned with system functionality, depicted using class diagrams and state diagrams.
- Process View: focuses on system runtime behavior, dealing with dynamic elements, and addressed using sequence diagrams, communication diagrams, and activity diagrams.
- Development View: concerned with software administration, depicted using UML Component diagrams and Package diagrams.
- Physical View: portrays the system from the perspective of a system engineer, documented using blueprints.
Architectural Evaluation
- Evaluating the design to ensure it addresses critical requirements.
- Informal and internal evaluation, or formal evaluation by an external team.
Quality Attributes
- Measurable or testable properties of a system to satisfy stakeholders’ needs.
- Architectural model: a high-level model without implementation information.
Design Guidelines and Layered Architectures
- Components at level X should only interact with APIs of components in level X-1.
- Issues in architectural choice, including data type and updates, change frequency, and system execution platform.
