1.What is the purpose of software architecture?
Software architecture serves several key purposes:
Structuring: It defines the overall structure of the system, specifying how components will be organized and how they will interact.
Facilitating understanding: It provides a clear and comprehensible view of the system, making it easier for developers, architects, and other stakeholders to understand.
Guiding development: It offers a framework for implementation, ensuring that the software is built coherently and meets established requirements.
Managing risks: It identifies and mitigates potential risks, such as performance or scalability issues, through early planning and design.
Improving quality: It contributes to software quality by promoting solid design practices and component reuse.
2.What are some different principles of software architecture?
The principles of software architecture can vary, but some commonly accepted ones include:
Separation of concerns: Divides the system into components or modules with clearly defined and well-contained responsibilities.
Modularity: Structures the system into independent modules or components that can be developed, tested, and maintained in isolation.
Abstraction: Hides complex internal details of a component or system, exposing only the necessary interfaces for interaction.
Encapsulation: Protects the internal state of a component from unauthorized access or modifications, ensuring that interactions occur only through public interfaces.
Reusability: Designs components so they can be reused in different contexts or systems, reducing redundancy and improving efficiency.
Scalability: Allows the system to adapt to growth in terms of users, data, or load without requiring a complete redesign.
Flexibility and extensibility: Facilitates modifications and extensions to the system without negatively impacting existing functionality.
