Software design aims to achieve all of these objectives: meeting user requirements, ensuring efficiency and scalability, and guaranteeing reliability and security.

Composite is not a design pattern; it is a structural pattern that describes how objects can be composed into larger structures.

A software architecture serves all of these purposes: defining the system's structure, specifying its components and relationships, and guiding its implementation and evolution.

Layered Architecture is not an architectural style; it is a structural pattern that describes how a system can be organized into layers.

Abstraction is the fundamental principle of object-oriented programming, which involves hiding the implementation details of an object and exposing only its essential characteristics.

Design patterns do not directly impact the performance of a software system. They are primarily concerned with improving the design and structure of the system.

A software designer plays a crucial role in translating user requirements, creating a technical design, planning the implementation, and ensuring the quality and performance of the software system.

Performance is not a design metric; it is a measure of the system's runtime behavior.

A software design review serves all of these purposes: identifying design flaws, ensuring compliance with requirements, facilitating communication, and improving the overall design quality.

Wireframes are not specifically used for software design; they are commonly used in web and UI design to create visual representations of user interfaces.

Refactoring aims to achieve all of these objectives: improving code structure, enhancing readability and maintainability, and optimizing performance and efficiency.

Scalability is not a design principle; it is a quality attribute that describes the system's ability to handle increasing demands or workloads.

A software design document serves all of these purposes: providing an overview of the design, documenting decisions and choices, and facilitating communication.

Singleton is not an anti-pattern; it is a design pattern that restricts the instantiation of a class to only one object.

Software design optimization primarily focuses on improving the performance and efficiency of the system, while also considering factors like complexity, maintainability, scalability, and reliability.
