What are the 4 elements that make up a software architectural style?

The architecture encompasses four distinct system components (software, hardware, databases, and people).

What are the four software design models?

Therefore, the four (4) primary models of software development methods are Linear Sequential (Waterfall), Incremental Development (ID), Reuse-Oriented (Rapid Application Development ; RAD), and Rational Unified Process (RUP).

What are the three examples where architecture elements are applied?

There are three elements in computer architecture. These elements are input/output devices, internal devices and how computer works.

What are the three types of models?

Contemporary scientific practice employs at least three major categories of models: concrete models, mathematical models, and computational models.

What is the design model?

The design model is based on the analysis and architectural requirements of the system. … It represents the application components and determines their appropriate placement and use within the overall architecture.

What are the benefits of using architectural styles?

The main benefits of the layered architectural style are:

• Abstraction. Layers allow changes to be made at the abstract level. …
• Isolation. …
• Performance. …
• Testability. …
• Independent.

What is architectural style and pattern?

An architectural style is a central, organizing concept for a system. An architectural pattern describes a coarse-grained solution at the level of subsystems or modules and their relationships. A system metaphor is more conceptual and it relates more to a real-world concept over a software engineering concept.

What are the two types of design model?

Product design consists of two types of designs, engineering design and industrial design. Mostly engineering design in product design has been referred to as mechanical design. Engineering design in product design is responsible for designing internal parts and its result is layout design.
